The modification of surface via polymer coating has been known to eliminate the protein adsorption. With this regard, the aldehyde functional group is found to interact readily a variety of biomaterials such as protein or DNA. In this study, poly(poly(ethylene glycol) methacrylate-co-4-formylphenyl methacrylate) brushes prepared by surface-initiated atom transfer radical polymerization(SI-ATRP) technique from substrates modified with a triethoxysilane-based ATRP initiator. After preparation of polymer brushes, amino-terminated DNA strands were immobilized on substrate. Then, it could be confirmed to interact with polymer brushes and bio-materials as the fluorescence images. The preliminary results for synthesis of surfaces coated PEGMA-co-PFPMA polymer will be discussed for various bio-application fields. |
