Oxygen-Rich Plasma-Polymerized Coatings for QCM Biosensing
2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE)(2020)
摘要
Thin reactive polymer surfaces are attractive in the field of bio applications, in particular, when they have the ability to bind biomolecules while providing a great level of stability in aqueous environment. Plasma polymerization techniques enable a fast and eco-friendly procedure for the preparation of thin functional polymer films. In this paper we report on the generation of highly functional oxygen-rich plasma-polymerized (pp) coatings with great level of stability in water. A quartz crystal microbalance (QCM) biosensor was successfully developed by using a plasma polymer film as a matrix layer for antibody immobilization. The developed QCM biosensor presented a stable baseline during the measurements and exhibited selective and high response to the analyte.
