INBT Director Speaks at JHU Alumni Event

By Angela Roberts (published as Back to the Classroom at Alumni College*)

“Our goal,“ said Peter Searson, director of Johns Hopkins’ Institute for NanoBioTechnology (INBT), “is to establish Hopkins as the world leader in nanobiotechnology. Or, as I like to say, world domination.“ The 40 or so alumni gathered in Hodson Hall appreciated Searson’s humor, especially at the beginning of an intensive, hourlong lecture on the characteristics of the very tiny things the INBT faculty researches.

Searson, who helped launch the INBT in 2006, was one of two Whiting School professors who hosted Alumni College during the Johns Hopkins Homecoming and Reunion in April. He and civil engineering professor Tony Dalrymple, who spoke on “Natural Hazards: Lessons Learned from the Tsunami and the Hurricane,“ led independent sessions open to all alumni, during which they explained their research and the latest developments in their fields.

Mac McLeod ’57 and his wife, Lenore Danielson, who were visiting from their home in New Jersey, attended Searson’s morning lecture. “Professor Searson is one of the best lecturers I’ve heard,“ McLeod commented. “It’s a fascinating field and he’s a fascinating teacher. It makes you feel like you’d like to go back to school and be in his class. It leaves you with a lot to think about, and it’s amazing to learn that the cost of solving the problems they’re working on is so high.“ His wife interjected, “And to realize that the cost of not solving them is equally high.“

Searson’s presentation began with talk of size and scale. He explained that a “bucky ball“—a fundamental building component in the world of nanobiotechnology—is only a nanometer wide. By comparison, a single strand of a human hair is 100,000 nanometers wide. “We can make materials that are smaller than cells, which means that we can build things that can go into cells and deliver drugs,“ he noted. He went on to discuss how nanobiotechnology engineers and scientists are searching for new therapies, new diagnostic tools, and a better understanding of the relationship between cells and disease.

While alumni from ages 30 to 90 listened intently, Searson continued on to explain the logistics of shrinking things to the nano scale, such as the discovery that when something gets smaller, a higher percentage of its atoms are on the surface. The result? Everything from fibers for athletic clothing that “wick away“ liquid to drug delivery systems that target cancer cells.

Searson’s lecture ended with projections for what the future of nanobiotechnology holds in store for the world. “We will be able to take a ‘smart pill’ that will be programmed to report on its position and status in the body before releasing the correct dose of drugs,“ he predicted. Searson believes Johns Hopkins will be at the forefront of such discoveries, and he predicts we will see this technology hit the marketplace within decades.

HHMI and NIBIB Officers Pay Positive Visit to Hopkins NBMed Program

In December 2005, Johns Hopkins University received a $1 million grant from the Howard Hughes Medical Institute to establish a graduate training program in nanotechnology for biology and medicine (NBMed). The goal of the NBMed program is to train graduate students with various undergraduate backgrounds at the multidisciplinary interface of nanotechnology, biology, and medicine and involves faculty from the Johns Hopkins School of Medicine, the Whiting School of Engineering, and the Krieger School of Arts and Sciences.

First Nano-Bio Symposium at Hopkins a Great Success

Johns Hopkins University held its first Nano-Bio Symposium on Friday, April 27, 2007. The event, organized by the Institute for NanoBioTechnology, took place at the Homewood Campus. “We had a great program and the symposium went extremely well“, says Peter Searson, Director of INBT. “Based on comments from those in attendance, I think it was a great success“.

The speaker session, which took place in Remsen Hall, was attended by an estimated hundred and fifty students and faculty from Hopkins and local universities, as well as representatives from government, industry, and venture capital firms interested in nanobiotechnology.

The featured talks covered a wide range of topics in nanobiotechnology, from the use of nanotools to gain new insight in cell adhesion, to the development of new worm-like nanoparticles as drug delivery carriers, to the development of fluorescence-based molecular moieties to probe gelation processes in biomaterials for tissue engineering applications. Wendy Sanhai of FDA talked about the challenges that her organization is facing with the rapid growth of nano-based biotechnologies and Piotr Grodzinski of the National Cancer Institute discussed funding opportunities in nanobiotechnology at NCI.

A diverse group of speakers from academic and government institutions was brought together for the symposium. The group included Michael P. Sheetz, professor of biological sciences at Columbia University; David J. Mooney, professor of bioengineering at Harvard University; Gunter Oberdorster, professor of environmental medicine at the University of Rochester; Dennis Discher, professor of chemical and biomolecular engineering at the University of Pennsylvania; Gang Bao, professor of biomedical engineering at Georgia Tech; Wendy Sanhai, Senior Scientific Advisor at the Food and Drug Administration; and Piotr Grodzinski, Director of the Nanotechnology Alliance for Cancer at the National Cancer Institute.

Poster Session

During the afternoon a poster session was held in the Mattin Center where over one hundred poster presentations were on display offering a broad overview of current nano-bio research efforts at the School of Medicine, the School of Engineering, the School of Public Health, and the School of Arts and Sciences at Hopkins. “I am very pleased that we had so many posters, it shows how eager researchers are to share their work and find out what others in the Hopkins community are doing“, says Denis Wirtz, Associate Director of INBT. The organizers also noted the overall high quality of the posters.

Four best posters were each awarded a $50 Barnes and Noble gift card. Michael Edidin, Professor of Biology in the Krieger School for Arts and Sciences and chairman of the judges, explained that the posters chosen had a scientific idea to test and used nanoscience or some other aspect of nanotechnology to address the problem. “We were also swayed by clarity of the poster and by the presentations made“, he said.

Curcumin, an element found in the cooking spice turmeric has long been known to have positive effects against certain types of cancer. Effective treatments based on curcumin however have been limited due to its poor dissolving capabilities in water based substances, leading to low absorption rates when ingested. Researchers affiliated with the Institute for NanoBioTechnology at Johns Hopkins University report to have overcome this problem by encapsulating free curcumin with a polymeric nanoparticle, creating nanocurcumin.
