Technique controls nanoparticle size, makes large numbers
Date:12/4/2007

eeling is that you have to be proactive, make sure everything is OK and then go, so here you are trying to be as cautious as possible, said Biswas.

Biswas work focuses mainly on making the nanoparticles, but his research has led to a variety of applications and collaborations. Biswas is currently collaborating with Sam Achilefu, Ph.D., associate professor of radiology in the Washington University School of Medicine. Achilefu is working to selectively deposit imaging agents. Rather than flood a cancer patients body with a drug during chemotherapy, for example, nanotechnology and selective deposits could deliver and concentrate the drug in the region of the tumor.

These are very preliminary results, said Biswas, but were getting some neat results. So there are some cautious examples, like toxicology, but then there are many useful applications.

Biswas also stresses the importance in the global marketplace. Nanotechnology has the potential to clean up water to provide drinking water for rural populations worldwide. Such efforts make a big social message, said Biswas. Renewable energy is yet another possibility in the realm of nanotechnology.

The possibilities of nanotechnology are endless, and everyday Biswas embarks on this exciting journey.

Thats the beauty here. At Washington University we have a very strong aerosol science and technology group, I would say one of the strongest, in this area, said Biswas. Furthermore, there are many collaborators in different disciplines where we can explore new application areas. So our ability to make tailor-made nanoparticles with very tight control on properties will allow more applications to be invented. Thats the driving force the ability to synthesize nanoparticles; they are the building blocks of nanotechnology.
