The feasibility of using protein A to immobilize antibody on silicon surface for a biosensor with imaging ellipsometry was presented in this study. The amount of human IgG bound with anti-IgG immobilized by the protein A on silicon surface was much more than that bound with anti-IgG immobilized by physical adsorption. The result indicated that the protein A could be used to immobilize antibody ...

Light emitted from a source into scene can undergo complex interactions with multiple surfaces of different material types before being reflected towards detector. During this transport, every surface reflection and propagation is encoded in the properties photons that ultimately reach detector, including travel time, direction, intensity, wavelength polarization. Conventional imaging systems c...

The dielectric functions of InP, IIla.53 Gao.47 As, and 1110.75 Gao.2S Aso.s P 0.5 epitaxial layers have been measured using a polarization-modulation spectroscopic ellipsometer in the 1.5 to 5.3 eV region. The oxide removal procedure has been carefully checked by comparing spectroscopic ellipsometry and x-ray photoelectron spectroscopy measurements. These reference data have been used to inves...

Abstract The Mueller matrix is a mathematical description of how light altered by an optical element or sample under study. It describes both intensity (irradiance) and polarization changes, including reduction the total polarization. spectroscopic ellipsometry has gained recent popularity in optics semiconductor communities as effective means to characterize complex structures anisotropic mate...

There is great interest in the development of alternatives to noble metals for plasmonic nanostructures. Transition metal nitrides are promising due their robust refractory properties. However, photophysics these nanostructures, particularly hot carrier dynamics and photothermal response on ultrafast timescales, not well understood. This limits implementation applications such as catalysis or s...
