Synthesis of graphitic carbon nitride nanosheet and its application for determination of Captopril by spectrofluorimetry method

In this study, nanoplates of graphite carbon nitride are synthesized by thermal method and optical properties and fluorescence intensity are investigated. In the following, these nanoplates are analyzed by a Scaning Electron Microscopy(SEM) . After that, the fluorescence intensity of synthesized nanoplates in the presence of captopril medicine is examined and is expected to reduce the flurosic intensity of the nanoplates due to the presence of nitrogenous substitute (substrate). In the following, various variables affecting the interaction of medicine and nanoplates are investigated. So, by finding optimal values, the best fluorescence sensor response range is plotted relative to the amount of medicine. At the end, A system designed to accurately determine the levels of captopril in the pharmaceutical and biological samples such as urine.
