Interplay Between Surface Chemistry and Optical Behavior of Semiconductor-biomolecule Functionalized Sensing Systems: An Optical Investigation by Spectroscopic Ellipsometry
Published online by Cambridge University Press: 01 February 2011
Abstract
Chemical functionalization of bio-molecules, including hemin (an iron porphyrin) and bovine albumin onto Si (100) and GaAs (100) surfaces is reported. Spectroscopic ellipsometry analysis on the optical response of functionalized surfaces provides information on molecular coverage and effective thickness as well as the kinetics of surface attachment. Topographic features of the chemically functionalized surfaces are investigated by atomic force microscopy
