Mar 19 | New To Market
At the AudiologyNOW! 2010 show in San Diego next month, UK-based coatings company P2i will display their relatively new Aridion liquid-repellant nano-coating. Designed for exposure to humidity or sweat, the polymer layer is applied by a pulsed ion gas process that lower’s the hearing aid’s surface energy, coaxing water away from delicate components.

Magic bullets, also called silver bullets, because of the folkloric belief that only silver bullets can kill supernatural creatures, remain the goal of drug development efforts today. A team of scientists at Washington Univ. in St. Louis is currently working on a magic bullet for cancer. But their bullets are gold rather than silver.

The film "Avatar" isn't the only 3-D blockbuster making a splash this winter. A team of scientists from Houston's Texas Medical Center this week unveiled a new technique for growing 3-D cell cultures, a technological leap from the flat petri dish that could save millions of dollars in drug-testing costs.

A nanoparticle growing in popularity as a bactericidal agent has been shown to be toxic to fish, according to a Purdue Univ. study. Tested on fathead minnows—an organism often used to test the effects of toxicity on aquatic life—nanosilver suspended in solution proved toxic and even lethal to the minnows.

Researchers have been able to see how heart failure affects the surface of an individual heart muscle cell in minute detail, using a new nanoscale scanning technique developed at Imperial College London. The findings may lead to better design of beta-blockers.

Taking gold nanoparticles to the cancer cell and hitting them with a laser has been shown to be a promising tool in fighting cancer, but what about cancers that occur in places where a laser light can’t reach? Scientists at the Georgia Institute of Technology have shown that by directing gold nanoparticles into the nuclei of cancer cells, they can not only prevent them from multiplying, but can kill them where they lurk.
