Safer Nanoparticles Spotlight Tumors, Deliver Drugs
February 22, 2009
Nanoparticles promise to illuminate tiny tumors and precisely deliver drugs, but many worry about the safety of nanoscale materials. Now a team of scientists has created miniscule flakes of silicon that glow brightly, slowly release cancer drugs, then break down into harmless by-products. They are the first luminescent nanoparticles to be purposely designed to minimize toxic side effects and this is the first study to image tumors using biodegradable silicon nanoparticles, the scientists say.

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) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
