Catalytic Growth of Au Nanoparticles by NAD(P)H Cofactors: Optical Sensors for NAD(P)⁺‐Dependent Biocatalyzed Transformations

Abstract

Gold-plated gold: NAD(P)H cofactors mediate the catalytic growth of Au nanoparticles in the presence of AuCl4− and CTAB (cetyltrimethylammonium bromide; see picture). The process allows for the optical detection of the cofactors and the analysis of NAD(P)+-dependent biocatalyzed transformations in solutions and on surfaces.
