Abstract

For bio-probe applications, a bio-film has to be attached to the nanoparticle surfaces to react with virus. However, the surfaces of many nanoparticles are not ideal for these particular bio-films. To provide an adhesive interface between the bio-film and the nanoparticle substrate, an ultrathin polymer film such as polystyrene and acrylic acid was deposited on several nanoparticles and carbon nanotubes using a plasma polymerization treatment. High Resolution Transmission Electron Microscopy (HRTEM) experiments showed that an extremely thin polymer film was uniformly deposited on the surfaces of these nanoparticles and nanotubes. The deposited films were characterized by depressive energy spectrum (EDS) and infrared spectrum (FTIR). The deposition mechanism is discussed.
