| titleOfInvention | Preparation method and application of water-soluble green fluorescent silicon quantum dots |
| abstract | The invention discloses a preparation method of water-soluble green fluorescent silicon quantum dots, which comprises the steps of placing a container with absolute ethyl alcohol in a constant-temperature oil bath, and adding a silane coupling agent and a reducing agent into the container in sequence; stirring for 10-120min, and cooling the solution obtained after the reaction to room temperature to obtain the water-soluble green fluorescent silicon quantum dot crude product. When the absolute ethyl alcohol is creatively used as a reaction solvent, the absolute ethyl alcohol can control the silanization reagent to slowly hydrolyze to generate silanol molecules, so that the synthesis of small-particle silicon quantum dots is facilitated, and meanwhile, the absolute ethyl alcohol can dissolve the silanol, so that the silanol is more stably present in the solution, and the condensation of the silanol is reduced. The silicon quantum dots prepared by the invention have simple and convenient synthesis method; the quantum yield is high; the specific recognition ability to ascorbic acid is strong, the minimum detection concentration can reach 0.04 mu M, and the probe is an ideal biological probe suitable for detecting trace markers in biological systems. |
