For years scientists and dieticians have argued over the health benefits of dietary fat. Research published this week, however, shows that piggybacking onto natural fat absorption pathways can dramatically enhance the utility of some drugs.
In a set of studies in mice bearing human tumors, nanoparticles designed to bind to a protein called P-selectin successfully delivered both chemotherapy drugs and targeted therapies to tumor blood vessels.
Using a unique combination of advanced computational methods, chemical engineers have demystified some of the complex catalytic chemistry in fuel cells - an advance that brings cost-effective fuel cells closer to reality.
A light beam passing through such a material splits and forms a characteristic pattern consisting of numerous bright spots on a projection screen. The researchers found that the number of these spots corresponds exactly to the number of scattering microscopic particles in the optical material.
