Hyperthermia treatment of cancer using magnetic nanoparticles: Detailed elucidation of heat generation mechanism

Scienists have investigated theoretically the mechanism of hyperthermic potentiation of cancers using magnetic nanoparticles, which enables selective heating of hidden micro cancer tissue, and clarified the fact that the nanoparticles under large magnetic fields form unique oriented states, depending respectively on subtle differences in their local environment in the cancer tissue and consequently affect the optimum heating conditions.

Researchers develop paint-on solar cells (w/video)

Imagine if the next coat of paint you put on the outside of your home generates electricity from light-electricity that can be used to power the appliances and equipment on the inside. A team of researchers at the University of Notre Dame has made a major advance toward this vision by creating an inexpensive "solar paint" that uses semiconducting nanoparticles to produce energy.

Silk microneedles deliver controlled-release drugs painlessly

Bioengineers at Tufts University School of Engineering have developed a new silk-based microneedle system able to deliver precise amounts of drugs over time and without need for refrigeration. The tiny needles can be fabricated under normal temperature and pressure and from water, so they can be loaded with sensitive biochemical compounds and maintain their activity prior to use. They are also biodegradable and biocompatible.
