PITTSBURGH—Carnegie Mellon University scientists have developed tiny, spherical nanogels that uniformly release encapsulated carbohydrate-based drugs. The scientists created the nanogels using atom transfer radical polymerization (ATRP), which will ultimately enable the nanogels to deliver more drug directly to the target and to dispense the drug in a time-release manner.The nanogels — only 200 nanometers in diameter — possess many unique properties that make them ideal drug-delivery tools, according to Daniel Siegwart, a graduate student in University Professor Krzysztof Matyjaszewski’s laboratory at Carnegie Mellon. Siegwart will present his research Monday, Aug. 20 at the 234th national meeting of the American Chemical Society in Boston.
