In groundbreaking research, scientists have demonstrated the ability to strategically attach gold nanoparticles - particles on the order of billionths of a meter - to proteins so as to form sheets of protein-gold arrays. The nanoparticles and methods to create nanoparticle-protein complexes can be used to help decipher protein structures, to identify functional parts of proteins, and to "glue" together new protein complexes.

Greystone Associates Analyzes the Impact of Protein and Peptide Drugs on Chronic Disease Segments

Using an innovative method to control the movement of Escherichia coli in a chemical environment, Emory University scientists have opened the door to powerful new opportunities in drug delivery, environmental cleanup and synthetic biology. Their findings are published online in the Journal of the American Chemical Society and will be published in a future print issue.

Researchers at the University of Pennsylvania School of Medicine & School of Engineering and Applied Science have discovered a better way to deliver drugs to tumors. By using a cylindrical-shaped carrier they were able sustain delivery of the anticancer drug paclitaxel to an animal model of lung cancer ten times longer than that delivered on spherical-shaped carriers.
