A simple method for preparing organic-inorganic composite particles based on poly (DL-lactic acid) (PLA) microbubbles and gold nanoparticles is presented in this study. PLA microbubbles are first prepared using a double emulsion-solvent evapouration technique. The surfaces of the prepared PLA microbubbles are modified by a cationic surface active agent, cetyltrimethylammonium bromide, which provides...
Patterned carbon nanotube arrays (PCNTAs) with reduced density and length were developed with polystyrene sphere masked catalyst dots followed by the plasma enhanced chemical vapour deposition method. The nanotubes were then uniformly coated with electropolymerised polypyrrole (PPy). The coating thickness was conformally adjustable. Gold nanoparticles (AuNP) together with glucose oxidase (Gox) were...
