Abstract

Polyhydroxyalkanoate (PHA) synthase attached to gold nanoparticles (AuNP) produce poly(3-hydroxybutyrate) (PHB) upon the addition of 3-hydroxybutyrate- CoA, and then coalesce to form micrometer-sized AuNP-coated PHB granules. These AuNP-coated PHB granules are potential theranostic agents that have enhanced imaging capabilities and are capable of heating upon near-infrared laser irradiation. The AuNP-coated PHB exhibited 11-fold enhancement in surface-enhanced Raman scattering over particles prior polymerization. Stained AuNP-coated PHB exhibited a 6-fold enhancement in fluorescence intensity as well as a 1.3-fold decrease in photobleaching rate compared to PHB granules alone. The granules were also shown to emit heat when illuminated at 808 nm with a 3.9-fold increase in heating rate compared to particles alone. © 2010 American Chemical Society.
