Paper Abstract

In this paper, a simple combination of spin-coating fabrication techniques and cost-efficient polymer material for the fabrication of optoelectronic NO2 sensor was investigated. A surface plasmon resonance (SPR) sensor was fabricated by chitosan thin films immobilized on the gold plasmonic active layer. Sensing structures were formed on the glass slides covered 50 nm thick Au films by spin-coating method from liquid chitosan salt phase. Polymeric thin film work as sensitive elements and transducer to get optical response from environment at room temperature (RT).
