Drug-embedded Microparticles Bolster Heart Function in Animal Studies
October 19, 2008
Tiny polymer beads embedded with anti-inflammatory drugs can reduce damage to the heart when injected into rats' hearts after a simulated heart attack. The beads (average size: 1/50 of a millimeter wide) are made of a "polyketal" material that breaks down over a few weeks in the body. Because polyketals are less inherently inflammatory than other biodegradable polymers, they could be used to treat several inflammatory diseases.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
