Dutch researcher successfully packages enzymes Dutch researcher Saskia Lindhoud has discovered a new way to package enzymes by causing charged polymers to form a 'ball of hair' around these. Her approach significantly increases the utility of the enzymes. For example, healthy enzymes with a foul taste can be packaged in such a way that they are released in the stomach without being tasted. Enzymes are molecules that can trigger specific chemical reactions. They are responsible for the taste...

Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge. Researchers demonstrated that the positive electrical charges of calcium ions "” just like the calcium in teeth and bone "” can form bridges between...

 In a presentation today (Aug. 19) to the American Chemical Society meeting, Ankit Agarwal, a postdoctoral researcher at the University of Wisconsin-Madison, described an experimental approach to wound healing that could take advantage of silver's anti-bacterial properties, while sidestepping the damage silver can cause to cells needed for healing.Silver is widely used to prevent bacterial contamination in wound dressings, says Agarwal, "but these dressings deliver a very large load of...
