A time efficient and green synthesis of polymer composites coated with gold nanoparticles


Jun - Oct 2014 @ Dr. Guofang Chen's nanomaterials lab, St. John's University


Worked to develop a time efficient and green method for synthesizing polymer composites coated with gold nanoparticles (AuNPs). The AuNP conjugated polymer composites were tested for their catalytic and artificial enzyme properties.


Metallic nanostructures such as gold, have exhibited promise as drug delivery systems and industrial scale catalysts. As differently shaped gold nanostructures exhibit unique properties, it is important to be able to efficiently control their shape formation. Conjugated gold nanostructures are desirable because they are recyclable catalysts. The purpose of this investigation was to control the shape and size of nanostructures synthesized on and via poly-(glycidyl methacrylate) (PGMA) or poly-(glycidyl methacrylate)@poly-(allylamine hydrochloride) (PGMA@PAH) colloidal spheres.
