Embodiment 1
[0040] This embodiment relates to a new method for preparing carbon nanoclusters, the method comprising the following steps:
[0041] Using glucose as the carbon precursor and leucine as the auxiliary reagent, the fluorescent carbon nanoclusters were prepared by reacting in an ethylene glycol medium, specifically:
[0042] (1) At room temperature, weigh 0.5g glucose and 0.5g leucine, dissolve them in a 25mL ethylene glycol round-bottomed flask under magnetic stirring, add concentrated phosphoric acid to the mixture, and make a mass ratio of 15 % ethylene glycol phosphoric acid solution, after the reactants are completely dissolved, heat to reflux for reaction, keep the temperature at 140°C and keep the reaction for 60 minutes, the concentration of the reaction solution turns from colorless and transparent to a dark brown solution, stop the reaction, cool and purify and separate.
[0043] (2) centrifuge the mixed solution obtained in step (1) at 5000r / min, and discard the preci...
Embodiment 2
[0048] Using citric acid as a carbon precursor and glutathione as an auxiliary reagent, the fluorescent carbon nanoclusters were prepared by reacting in an ethylene glycol medium, specifically:
[0049] (1) At room temperature, weigh 1g of citric acid and 0.5g of glutathione, dissolve them in a 25mL ethylene glycol round-bottomed flask under magnetic stirring, add concentrated phosphoric acid to the mixture, and make a mass ratio 5% phosphoric acid ethylene glycol solution, after the reactants are completely dissolved, heat to reflux for reaction, keep the temperature at 160°C and keep the reaction for 80 minutes, the concentration of the reaction solution turns from colorless and transparent to a dark brown solution, stop the reaction, cool and purify and separate.
[0050] (2) centrifuge the mixed solution obtained in step (1) at 8000r / min, and discard the precipitate.
[0051] (3) Put the supernatant in step (2) into a dialysis bag with a molecular weight cut-off of 500, pl...
Embodiment 3
[0055] Using citric acid as a carbon precursor and horseradish peroxygenase as an auxiliary reagent, react fluorescent carbon nanoclusters in a glycerol medium, specifically:
[0056] (1) At room temperature, weigh 1g of citric acid and 0.25g of horseradish peroxygenase, dissolve them in a 25mL ethylene glycol round-bottomed flask under magnetic stirring, and add concentrated phosphoric acid to the mixture to prepare the mass Compared with 20% phosphoric acid ethylene glycol solution, after the reactant is completely dissolved, heat to reflux for reaction, keep the temperature at 180°C and keep the reaction for 120min, the concentration of the reaction solution turns from colorless and transparent to a dark brown solution, stop the reaction, cool and purify and separate .
[0057] (2) centrifuge the mixed solution obtained in step (1) at 7000r / min, and discard the precipitate.
[0058] (3) The supernatant in step (2) is placed in a large amount of ultrapure water in a dialysi...
