We have a new paper out in ACS Biomaterials Science and Engineering, published in collaboration with my old lab mates in the bio-group of the Air Force Research Laboratory.  In this paper, we describe a very interesting process wherein FlgA3, a Au binding peptide, switches chirality from the D- peptide to the L- peptide during nanoparticle synthesis.  Evidence is presented the suggest in-situ catalysis from D- to L- enantiomer at the Au surface, which, oddly enough, may help point to why the majority proteins and peptide on Earth are of the L- variety.  Cool stuff!
