Surface modification of porous alumina membranes by collagen layers: Performance and characterization

In this study, surface properties of alumina microfiltration membranes were modified by spin coating the surface with thin layers of collagen while controlling other critical surface properties such as pore size and surface charge. Collagen was spin deposited in layers of 1, 3, 6 or 9 onto an alumina membrane surface and IR spectra confirmed the presence of collagen protein on the substrate layer. The surface topography and pore morphology were...
