Comparison of Raman integration maps. Optical images and Raman maps revealed a modified surface after anti-CD34 antibody immobilization. POSS-PCU-CD34 had a granite-like appearance on both optical and Raman integration. Detection of POSS and PCU –rich regions also revealed a chemically heterogeneous surface. Scale bar represents 5 μm.
