生体適合性ポリマー膜によるバイオインターフェースの創製とPDMSマイクロチップ電気泳動への応用

抄録

We prepared the biocompatible phospholipid polymer, poly [2-methacryloyloxyethyl phosphorylcholine (MPC)-co-3-(methacryloyloxy)propyltris (trimethylsilyloxy) silane (MPTSSi)]: PMMSi for the surface modification in microchannel of PDMS bioanalytical devices. The protein adsorption was resisted and electro-osmotic flow (EOF) was reduced on the PMMSi coated PDMS surface. The repeatable precision on electrophoresis was obtained, so it is expected the PMMSi coated interface is suitable for micro-bioanlysis.
