Addition of ceramic particles, fibers toughens polymer cartilage candidate after gamma exposure

By / October 11, 2011

Credit: F. Jacquot; Wikipedia. Although they are somewhat light on the details, researchers at the Changzhou Institute of Light Industry Technology (CIT) say they may have found a way to address fatigue problems associated with two materials of interest for use as cartilage-like coating material for joint prostheses. Led by Maoquan Xue, the CIT group wanted to see…

Sensitive sensor-packed microchip and new analytical model could test 100,000 protein–drug interactions in minutes

By / April 22, 2011

A microchip with a nanosensor array (orange squares) is shown with a different protein (various colors) attached to each sensor. Four proteins of a potential medication (blue Y-shapes), with magnetic nanotags attached (grey spheres), have been added. One medication protein is shown binding with a protein on a nanosensor.
