Paper Abstract

Nitric Oxide (NO) is a biological messenger molecule involved in multiple physiological processes, which plays an important role in the regulation of blood pressure, immune response, and neural communication. A novel fluorescent probe CdSe/PMMA nanocomposite was synthesized by a simple physical blending method for trace NO detecting. It was confirmed that the CdSe QDs are spherical and monodispersed in PMMA matrix adopting transmission electron microscopy and UV-Vis absorption spectroscopy. The sensitivity of CdSe/PMMA nanocomposite for NO detection and its optical properties were also investigated. The fluorescence intensity of CdSe/PMMA nanocomposite was obvious quenching in the presence of NO and the quenching mechamism was also discussed.
