On Being an Exhibitionist

As I type these words, I am sitting on an airplane returning from Denver to Atlanta, having just hosted an NRC exhibit booth at the Transducers 2009 conference. This conference is also known as the International Conference on Solid-State Sensors, Actuators, and Microsystems, so you can see why it is traditionally known as Transducers.

In recent years, the Nanotechnology Research Center has exhibited at a wide variety of scientific and trade conferences, with the goal of promoting awareness of the center among practitioners (academic, government, and commercial) of micro/nano research, fabrication and characterization. As you are probably aware, our role within the National Nanotechnology Infrastructure Network obligates Georgia Tech to encourage and support usage of our facilities by both internal and external (non Georgia Tech) users. Conference exhibits are one tool in the marketing arsenal that has proven effective in reaching out to the international research community. I have noticed several encouraging trends over the years that I have been attending conferences as an NRC representative.

First, Georgia Tech has growing name recognition, and is known for its activities, along with our NNIN partners, for the quality of its faculty and students, as well as its resources and capabilities. Many people were aware of the new Marcus Nanotechnology Building, if not by name, and were astounded to hear of its specifications.

Second, I find that after two years I don’t need to provide as lengthy an explanation of how we operate as a user facility, for either on-site, hands-on or remote usage. I cannot be sure if this is related to my first point above, or is due to the improved quality of our marketing materials (booth design and brochures).

Third, although there are a variety of other resources available to researchers for fabrication and manufacturing scale-up (foundry services), the NRC (and NNIN) remain one of the few options for direct, hands-on usage. Still, although people appear to value this capability, the vast majority of potential users would prefer to contract the processing to our staff. I remain perplexed as to why individuals are willing to cede control of their own research or processes, and I am seeking ways to further encourage on-site work by our external users.

Finally, depending on the venue, there emerge some common interests, and it is gratifying to realize that the NRC is almost always in a position to assist in these areas. At Transducers, the most common needs were deposition of piezoelectric materials, deep reactive ion etching, and electron beam lithography, all strengths of the NRC.

It is good to be home, but I think the hard promotional work, made easier by the pleasant venues and joy of travel, is paying off.

Alphabet Soup

Summer time always reminds me of food at the Nanotechnology Research Center. As anyone who has ever been a user or a staff member will tell you, the NRC, like my Jewish mother, will feed you until you beg for mercy. If it is not the bagels on Friday morning, the BBQ lunches, the catered vendor seminars, or the birthday cakes, then it is the edibles (usually bad for my diet) left in the Micro CafĂ© for the random hungry passerby. However, the alphabet soup I am referring to here is not the kind from the familiar red and white Campbell’s can, but rather the acronyms of the summer visitors that populate the NRC hallways, carrels, and cleanroom this time of year. And this summer, thanks to the efforts of NNIN Education Coordinator Nancy Healy and many others, it seems as if the assortment is more varied than ever.

If you see someone new in the Pettit or Marcus building, introduce yourself and ask them what program they are on. If they give you a single syllable answer that would be more at home in a game of Scrabble, here is a lexicon to help you out.

TAG – When I was in high school, I spent the summers mowing the lawn, watching TV, and working in my home darkroom. Through the Technology Association of Georgia and its new program of high school internships, there is now an opportunity for engineering-minded teens to work alongside seasoned NRC staff.

RET – As any teacher will tell you, student’s summer vacation is rarely a time for teachers to lounge on the beach with a drink and a trashy novel. Most teachers I know use this time (usually unpaid) for professional development, and the Research Experience for Teachers is a great way to gain some first-hand understanding of microfabrication and nanotechnology that they can incorporate into their curricula for the fall.

REU – I remember my first research experience in college; I worked in the Oral Physiology Lab of the Dental School where I counted taste buds on neonatal rats. More importantly, there was no formal mechanism or supporting organizations to help me acquire this position. Thankfully, most universities now promote, support, and fund undergraduate research as an important component in students’ education. The NSF-sponsored Research Experience for Undergraduates is a program of mentored research in a wide variety of science and engineering fields to encourage students to pursue graduate education and careers in these areas.

SURE and LEF – As the demographics of this country change, it is vitally important that we improve diversity within every area of science and engineering, and I am pleased that Georgia Tech graduates the nation’s largest contingent of African-American engineers. The Summer Undergraduate Research in Engineering/Science Program is designed to attract minority students to technical career areas. The Laboratory Experience for Faculty is an NNIN program to provide access to advanced research facilities to faculty from minority institutions, and the NRC has been privileged to host summer visitors in this program for the last two years.

At its heart, as a part of an institution of higher education, the NRC is a place to teach and to learn. This educational mission can come in many forms, from the research of undergraduate students, graduate students and post-docs (who are apprentices, after all) to preaching the benefits (and risks) of nanotechnology to future engineers and scientists (our school-age children), their teachers, and their parents (the voting and tax-paying public). Let's enjoy the summer's warm weather along with some alphabet soup.

Biotech, Nanotech, and BIO

Maybe you heard about it on the radio or read about it in the newspaper. Maybe you saw some of the many visitors clogging the streets of Atlanta or touring around Georgia Tech. The commotion was the annual conference of the Biotechnology Industry Organization (BIO) which took place at the Georgia World Congress Center from May 18-22.

BIO was unlike any scientific conference I have ever attended. With its focus on exhibition, both academic and industry achievements were showcased within state and national pavilions, and there was ample opportunity for corporate and political entities to mix, mingle, discuss, and deal. A highlight of the Georgia Pavilion was the announcement by Governor Sonny Perdue and Georgia Tech President Bud Peterson of the new Global Center for Medical Innovation (GCMI), which will be housed at Technology Enterprise Park, at the perimeter of Tech’s campus.

Although most of the attention was on the exhibition, I did attend several symposia that touched on the intersection of biotechnology and nanotechnology. In one session, titled “Transformational Tools: How New Research Technologies are Changing the Rules of the Game,” a panel of CEOs from both emerging and mature companies described a variety of new reagents and devices. Accuri Cytometers seeks to “democratize” the application of flow cytometry by developing a small and inexpensive flow cytometer for individual research labs that can compete with the larger units found in core facilities. Life Technologies (a recent merger between Applied Biosystems and Invitrogen) markets QDot probes for diagnostic applications. In an earlier session on cancer nanomedicine, Joe Beechem (VP, Corp. Res. Lab) elucidated the use of these quantum dot labels for single molecule detection in microfluidic flow channels. In particular, Joe described how the problem of non-specific binding can be evaded through the use of multiple colors which significantly improve the statistical odds of positive detections. The link between research and clinical genetics is shortened through the single molecule, whole genome analysis offered by BioNanomatrix. Finally, RainDance Technologies has commercialized a unique microdroplet platform that allows researchers to detect, sort, and capture individual picoliter environments at rapid rates. This venture stems from research at Harvard University, The Medical Research Centre in Cambridge, England, and the ESPCI in Paris. These examples highlight the path whereby nanoscale materials and devices will enhance the toolbox available for biotech discovery and applications.

While taking in the robust discussion of these novel technologies, I was struck by the realization that the theme of the BIO conference was the importance of both the utility and originality of technology itself. This point was driven home by one CEO who told the audience to forget about their own innovative, high-tech offerings and instead focus on the specific needs of the customers. This is not a lesson taught in graduate school, but one learned throughout the course of professional life.

It Starts with Tape

Many years ago I interviewed for a job with 3M. At that time, I was certain that I was destined for fame and fortune in academia-- after all, I had the sport coat with the patches on the elbows. With my newly-minted Ph.D. in hand, I had the audacity to tell the interviewer that I was not interested in making tape. Needless to say, the interview was brief, and I was not offered a position with 3M. It took a few years of maturing for me to realize how arrogant and ill-informed I had been.

This story came to mind recently as I have been thinking and reading about commercialization of nanotechnology. A recent editorial in Nature Nanotechnology (Vol. 4, pg. 1, January, 2009) entitled “The Other Nanotech” discusses this issue. In particular, it is pointed out that 2007 was a milestone year in which corporate R&D spending for nanotechnology ($6.6 billion) surpassed that of government spending ($6.2 billion). All of these research dollars are not going solely to develop the complicated and expensive devices we are familiar with in university nanoscale research. Rather, much of this money is being spent on commercial applications of nanotechnology that are or will be household products.

The assortment of commercial nanotechnology applications are inventoried on a terrific website run by The Project on Emerging Nanotechnologies which lists more than 800 products. The inventory includes the DeWalt power drill (available at Home Depot) which contains lithium iron phosphate nanocrystal batteries created by MIT-spinoff A123 Systems. This company was also mentioned this week in a story in the business section of the New York Times, where it was described that emerging U.S. automotive policy directed toward electric cars may speed the involvement of A123 in developing nanotechnology-based car batteries. However, interestingly, more than half of the products in the commercial nanotechnology inventory fall into the health and fitness category, which includes such items as cosmetics and sunscreens.

The important point here is that while industry is peddling “bulk nanotechnology” for seemingly mundane applications (the “other nanotech” of the editorial), they are funneling what they are learning about material properties, mass production, packaging, and stability into more high-tech and demanding applications in areas such as medicine, energy, and electronics. Even 3M currently has several nanotechnology products in areas such as dental restoratives and automotive window coatings. And you may have heard about the variety of academic and corporate labs developing adhesives based on the nanoscale structures found on gecko feet. I guess it all comes back to the tape.

Nano Everything

The American Chemical Society (ACS) runs a web site via its publications arm call ACS Nanotation. This site serves as a compendium of information and resources for the nanoscience and nanoengineering community. Journal article reviews, multimedia (images, video, podcast), career resources, calendar events and the like are all available in one convenient location.

One of the recent public relations/outreach activities of ACS Nanotation was a contest for the best video that answers the question “What is Nano?” The idea was to use creativity and humor, while maintaining scientific accuracy, to convey the significance and impact of nanotechnology to the YouTube generation. Videos were submitted and available for viewing during the first quarter of 2009, and the winners, selected by both a panel of judges (Critics’ Choice) and by popularity (People’s Choice), were announced earlier this week.

And the envelope please (with my comments added)...


Critics’ Choice and People’s Choice (1st Place): The Nano Song
Patrick Bennett, David Carlton, Molly Felz, Nola Klemfuss, Glory Liu, Ryan Miyakawa, Stacey Wallace, and Angelica Zen (University of California, Berkeley)
A musical number that made me think of Kukla, Fran and Ollie.

Critics' Choice (2nd Place): Introduction to Nanotechnology
Dan Graham (Asemblon Inc.)
Remember those film strips from elementary school (at least in the 1970s)?

People’s Choice (2nd Place): Nanotechnology Brings us Delicious New Solar Cells
Blake Farrow (University of Notre Dame).
Kitchen (mostly) science with wry commentary.

Check these out at your leisure (and there is plenty more where these came from on the ACS Nanotation website). You might learn something, and, if nothing else, I promise you will be entertained.

The NanoFANS Forum

Last Friday was the third installment of the NanoFANS (Focusing on Advanced Nano-bio Systems) Forum , a biannual symposium for the nanoscience and nanotechnology community held at the Georgia Tech NRC. This was the first major event held in the conference facilities of the Marcus building, and it was a bit of a shakedown cruise as we learned the ins and outs of the new audio-visual systems. Nevertheless, it was an extremely well-attended event, with nearly 150 pre-registrations – a number that could not be accommodated in the space within the Pettit building. Credit and kudos to Paul Joseph, NRC Senior Research Scientist, who has organized this event since its inception in 2008.
The theme of the symposium was Cancer Nanotechnology, and the three speakers all touched on the use of nanomaterials for cancer diagnosis and treatment. Shuming Nie (GT and Emory School of Biomedical Engineering) is one of the pioneers in development and application of semiconductor quantum dots as fluorescent labels, and he discussed their tunability using size, composition, and strain. QDs have progressed steadily over the past 10 years through in vitro cellular studies and in vivo animal studies, and human applications appear just around the corner. John McDonald (GT School of Biology) represents the successful collaboration between cancer biology and nanoscience through his work with Andrew Lyon on nanohydrogels for siRNA delivery and John Zhang on magnetic nanoparticles for capture of metastatic cells. Finally, Mostafa El-Sayed (GT Chemistry and Biochemistry) explained the unique electronic properties of nano-gold which are promising for spectroscopic and thermal generation applications in cancer detection and therapy.

If you missed this NanoFANS event, you will be able to find the talks on SMARTech , the library’s archive, when they are posted (along with the previous presentations). However, if you are interested at all in the intersection of nanotechnology and the life sciences, I recommend you not miss NanoFANS when it returns in the fall.

A Rising Nanotech Star

Philip V. Streich, an unassuming and polite 18 year-old, represents the future of nanotechnology research in this country.

I met Philip last year when he was a high school junior, at the 2008 Intel International Science and Engineering Fair (ISEF) in Atlanta. I led a team of judges who were selecting the best chemistry projects for special awards from the American Chemical Society. Although I did not speak with Philip during the two days of judging, I had this opportunity at the awards ceremony. Our team of judges unanimously awarded him the first place ACS award of $4000 for his research proving that carbon nanotubes can be dissolved in certain organic solvents such as N-methyl-2-pyrrolidone. He did this using light-scattering instrumentation he assembled from spare parts he found in the lab of his mentor, James Hamilton at the University of Wisconsin, Platteville. Oh, did I mention that Philip is home-schooled on the family’s 400 acre farm? As it turns out, we were not alone in our awe of his work and accomplishments-- Philip won additional awards totaling nearly $18,000 in 2008.

The previous year, as a sophomore, he was one of the three top winners of a $50,000 prize at ISEF 2007. He continues his streak this year, taking 3rd place in the Intel Science Talent Search (another $50,000 prize) and being selected by his fellow finalists for the Glenn T. Seaborg Award. These are just some of the many accolades he has won over the last several years. Not bad for a young man who is also a member of the 4H club, plays guitar and piano, and is treasurer of the Democratic Party of Grant County.

Finally, Philip is co-founder and co-owner of Graphene Solutions LLC, a company formed to commercialize the results of his research. You can find out more about Philip and his research from his Wikipedia entry, or from an interview on the Discovery channel, or by watching this YouTube video.

With Philip Streich entering the world of nanotechnology research (he will attend Harvard in the fall), the outlook is bright.
