The adhesion of bacteria on surfaces and the growth of biofilm are considered as critical phenomena in medical and industrial settings. Previous studies suggested that topographies and chemical properties of a surface are important in the adhesion of bacteria and the growth of biofilm on a particular surface. To further understand behaviors of bacteria on the multifunctionalized surfaces, we need to expand the library of surface chemistry on Si(100) surfaces with nano topography. This study attempts to understand the site specificity of oxidation on water etched Si(100) surfaces in early oxidation. We will further examine the placement of OH groups on the water etched Si(100) surfaces. The effect of the placement of OH groups on the wettability of the surfaces are also explored. Fourier transform infrared (FTIR) spectroscopy is used to analyzed the oxidation sites on the Si(100) surfaces. Contact angle measurements is taken to measure the wettability of oxidized surfaces.
