News From the Field
Safer Nanoparticles Spotlight Tumors, Deliver Drugs

February 22, 2009

new nanoparticles illuminating 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.
