Embodiment 1
[0091] Prepare and synthesize the material described in formula (1) of the present invention:
[0092] Take by weighing 0.1 gram of chitosan and join in 100 milliliters of deionized water, mechanically stir at room temperature for half an hour, so that chitosan dissolves completely, thereby obtain the homogeneous solution that mass volume percent concentration is 0.1%; Slowly add thiourea trioxide into the system, the molar ratio of thiourea trioxide and chitosan is 10:1, the feeding time is 30 minutes, and the reaction at room temperature is kept for 60 minutes; A mixed solution of amino acid, N-hydroxysuccinimide (NHS) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC·HCl) (solvent: 30mmol / L of 2-(N-morpholino)ethanesulfonic acid (MES) buffer solution) 20ml was added to the above-mentioned reaction solution, and the stirring reaction was continued at room temperature for 48 hours, wherein chitosan, arginine, NHS, EDC The molar ratio of the solution is 50...
Embodiment 2
[0096] Prepare and synthesize the material described in formula (2) of the present invention:
[0097] Weigh 0.1g carboxymethyl chitosan (the number average molecular weight is 2×10 5 Da, the degree of carboxymethyl substitution is 100%, and the degree of deacetylation is 100%), add 100mL deionized water, and mechanically stir evenly at room temperature, so that carboxymethyl chitosan is completely dissolved, thereby obtaining a mass volume percent concentration of 0.1% solution; weigh 2,3-epoxypropyltrimethylammonium chloride, dissolve in 50mL deionized water, and stir mechanically at room temperature; Ammonium chloride solution was slowly added to the carboxymethyl chitosan solution in 3 times, and the feeding time was 4 hours, and then stirred at constant temperature for 4 hours; Adjust the pH value of the solution to 5.0 and the salt concentration to 0.01M to obtain solution S1; weigh NHS and EDC (molar ratio is 1:10), dissolve in 30mL 0.01M pH 5.0MES / HCl buffer solution ...
Embodiment 3
[0101] Prepare and synthesize the material described in formula (3) of the present invention:
[0102] Weigh 0.35g carboxymethyl chitosan (the number average molecular weight is 2×105Da, the degree of carboxymethyl substitution is 100%, and the degree of deacetylation is 95%), add 35mL deionized water, and stir mechanically at room temperature to make the carboxymethyl chitosan Polysaccharides were completely dissolved to obtain a solution with a concentration of 1% by mass volume; weighed NHS and EDC (molar ratio 1:1), dissolved in 15mL 0.01M pH5.0MES / HCl buffer solution to obtain a catalyst solution; weighed Add arginine to the catalyst solution for activation, and stir at room temperature for 1 hour; pour the arginine activation solution into the carboxymethyl chitosan solution for 3 times, and react for 24 hours under stirring at 45°C; Hydroxylamine hydrochloride with an equimolar ratio of arginine was added to the reaction solution to terminate the reaction; the reaction ...
