A newly nano-sized device developed by a team of researchers including one of Indian-origin, is revolutionizing medicine by improving drug solubility and bio-distribution, and becoming likely to play an increasing role in the design of next generation nanoscale carriers of drug and imaging agents. The study by researchers from Duke University and the University of Southern California covers two classes of self-assembled, nanoscale medical delivery devices currently used to transport drugs and also imaging materials across physiological barriers that they, acting by themselves, would be unable to cross.
