| titleOfInvention | Novel enzyme-ratio-free fluorescence detection method for organophosphorus pesticide based on copper-doped carbon nanodots |
| abstract | The invention relates to the technical field of nano materials, catalysis and chemical sensing, and provides a novel enzyme-ratio-free fluorescence detection method for organophosphorus pesticides based on copper-doped carbon nanodots. The fluorescent copper-doped carbon nanodots with good stability and peroxidase activity are synthesized by adopting anhydrous copper chloride, tris (hydroxymethyl) aminomethane and L-dopa as starting materials through a one-step hydrothermal method, and the peroxidase activity of the copper-doped carbon nanodots is utilized to catalyze hydrogen peroxide to oxidize o-phenylenediamine to generate fluorescent oxidation state molecules 2, 3-diaminophenol oxazine, so that two fluorescence emission peaks of the copper-doped carbon nanodots and the 2, 3-diaminophenol oxazine are generated at 375 nm and 555 nm. The ratio of the fluorescence intensity at the two wavelengths is in a linear relationship with the concentration of the organophosphorus pesticide, so that the enzyme-free ratio fluorescence detection of the organophosphorus pesticide is realized. The sensor construction method is simple and easy to implement, does not need to use biological enzyme, is slightly influenced by probe concentration and environmental factors, and has the advantages of wide linear range and high sensitivity. |
