使用多参数表面等离子体共振分析仪MP-SPR表征聚合物-层的吸附和厚度: Polymers are extensively studied and often interactions play a key role in the product functionality. Two separate polymer interaction studies were conducted using label-free real-time Multi-Parametric Surface Plasmon Resonance (MP-SPR). Functionalization of nanocellulose surfaces was performed by adsorption of block copolymers. The e?cacy of anti-fouling of the PEG-based polymer brushes was quanti?ed by measuring adsorption of serum samples. Based on the MP-SPR measurements, polymers were further characterized in terms of thickness and adsorbed mass. Nanocellulose functionalization was con?rmed to be successful and -OH terminated 10 kDa PEG was found to be the best anti-fouling coating, producing 99% resistance.
