Protein Adsorption on the Surface of a Thin-Film Polymer Integrated Optical Waveguide

Volume 42, Number 1 (Jan. 1988) Page 68-72

Ives, J.T.; Reichert, W.M.


Protein adsorption (fluorescein labeled gamma globulin, FITC-IgG) on the surface of poly(styrene) thin-film optical waveguides was fluorescently detected. The time course of adsorption, the FITC-IgG fluorescence spectra, and the surface concentration estimates are presented. The results demonstrate the potential use of polymer optical waveguides as integrated optic evanescent sensors.
