Squishy Hydrogels May Be the Ticket for Studying Biological Effects of Nanoparticles
05/15/2013 - 13:58

A class of water-loving, jelly-like materials with uses ranges ranging from the mundane, such as superabsorbent diaper liners, to the sophisticated, such as soft contact lenses, could be tapped for a new line of serious work: testing the biological effects of nanoparticles now being eyed for a large variety of uses.

Nanoparticles loaded with bee venom kill HIV
03/08/2013 - 10:28

Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St. Louis have shown. The finding is an important step toward developing a vaginal gel that may prevent the spread of HIV, the virus that causes AIDS.

Trackable drug-filled nanoparticles - a potential weapon against cancer
03/04/2013 - 10:11

Tiny particles filled with a drug could be a new tool for treating cancer in the future. A new study published by Swedish scientists in Particle & Particle Systems Characterization shows how such nanoparticles can be combined to secure the effective delivery of cancer drugs to tumour cells - and how they can be given properties to make them visible in MR scanners and thus rendered trackable.

Changing Shape Makes Chemotherapy Drugs Better at Targeting Cancer Cells
02/27/2013 - 14:52

Bioengineering researchers at University of California, Santa Barbara have found that changing the shape of chemotherapy drug nanoparticles from spherical to rod-shaped made them up to 10,000 times more effective at specifically targeting and delivering anti-cancer drugs to breast cancer cells.

Researchers ‘Nanoweld’ by Applying Light to Aligned Nanorods in Solid Materials
02/21/2013 - 15:45

Researchers from North Carolina State University have developed a way to melt or “weld” specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to stronger, more resilient nanofibers and materials.
