Biocompatible Surface Preparation Using Amino-Functionalized Amylose

摘要

Aminopropyl amyloses with various degrees of substitution (DS) were prepared and investigated with respect to their surface modification properties.Poly(acrylic acid) was grafted to plasma-activated PVDF films,and the functional amylose was bound via amide linkage formation.Layer formation was confirmed by X-ray photoelectron spectroscopy.Contact angle measurements and surface MALDI-TOF mass spectrometry indicated a hydrophilic surface and minimization of protein adsorption.
