Biocompatible surface preparation using amino-functionalized amylose.
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.
