Paper Abstract

The photoluminescence of the porous silicon obtained by special procedure with the usage of the chemical and laser beam treatment of silicon crystal was investigated in water, buffer and solution containing sodium chloride. It was demonstrated that the intensity of the photoluminescence did not practically change at the above mentioned conditions as well as after antigen or antibody immobilization on the porous silicon surface. But this parameter of the photoluminescence dramatically decreased in case of specific immune complex formation on the silicon surface. The level of the photoluminescence extinguishing depended on duration and intensity of immune reaction. It is proposed to use discovered effect for creation of the immunosensors based on the direct registration of immunocomplex formation.
