By loading magnetic nanoparticles with drugs and dressing them in biochemical camouflage, researchers say they can destroy blood clots 100 to 1,000 times faster than a commonly used clot-busting technique.
BioTechniques - University of Illinois researchers have now devised a novel method to monitor how unfolded proteins diffuse inside the crowded environment of living cells and have found that their travel is significantly obstructed by their expanded size in tight spaces, as well as by chaperones that bind unfolded proteins to slow them down.
The outline of the lizard serves as a test object, as well as the conventional test pattern, a section of a so called Siemens star. The lizard’s tail and the converging rays of the Siemens star can be used to measure how well narrow lines will be reproduced in an image. With a diameter of six thousandths of a millimeter, the entire test object is about the size of a red blood cell. The smallest resolved structure has a width of 46 nanometers. Image: J. Geilhufe, HZB
