Therapeutic Nanoparticles Give New Meaning to Sugar-Coating Medicine
A research team at the National Institute of Standards and Technology (NIST) studying sugar-coated nanoparticles for use as a possible cancer therapy has uncovered a delicate balancing act that makes the particles more effective than conventional thinking says they should be. Just like individuals in a crowd respecting other people’s personal space, the particles work because they get close together, but not too close.

Tumors Feel the Deadly Sting of Nanobees
When bees sting, they pump into their victims a peptide toxin called melittin that destroys cell membranes. Now, by encapsulating this extremely potent molecule within a nanoparticle, researchers have created a potential new type of anticancer therapy with the potential to target a wide range of tumors.

Carbon Nanoparticles Toxic to Adult Fruit Flies But Benign to Young
Researchers at Brown University have discovered that certain types of carbon nanoparticles can be environmentally toxic to adult fruit flies, although they were found to be benign when added to food for larvae. The findings, published online in Environmental Science & Technology, may further reveal the environmental and health dangers of carbon nanoparticles.

Simultaneous Oxidation and Reduction of Arsenic by Zero-Valent Iron Nanoparticles: Understanding the Significance of the Core−Shell Structure
Increasing evidence suggests that nanoscale zerovalent iron (nZVI) is effective for the removal of arsenic from contaminated water, but the immobilization mechanism is unclear.

All-in-one nanoparticle: A Swiss Army knife for nanomedicine
Nanoparticles are being developed to perform a wide range of medical uses -- imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package.
