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! You can find the paper here: https://pubs.acs.org/doi/abs/10.1021/acsbiomaterials.9b00933
