Abstract Nonbiofouling, prevent accumulation of bioentities is an important issue in a wide range of biology and medical fields. We recently report about polysaccharide film and characterized of surface modification and biotinylation. Surface-Initiated Activators ReGenerated by Electron Transfer Atom Transfer Radical Polymerization (SI-ARGET ATRP) of acetylene-terminated hydroxyethyl methacrylate (AHEMA) and oligo(ethylene glycol) methacrylate (OEGMA) has been successfully performed in aqueous media at room temperature and subsequent coupling of a biotin ligand containing azide via click chemistry on the poly(AHEMA-co-OEGMA) films. We compared stability of polysaccharide film and polymeric films through many instruments for using fluorescence scanner, confocal microscope, scanning electron microscope (SEM), atomic force microscope (AFM), goniometer.
