preparation example Construction

[0025] A kind of supramolecular hydrogel preparation method containing silver nanoparticles provided by the embodiment of the present invention comprises the following steps:

[0026] Weigh the D-type Fmoc-Phe gel factor.

[0027] The D-type Fmoc-Phe gel factor is dissolved in a buffer solution with a pH value of 7.4 to obtain the first mixed solution, ensuring that the concentration of the D-type Fmoc-Phe gel factor in the first mixed solution is at 6-20mg / mL.

[0028] Shake the first mixed solution for 30s, then heat and dissolve at 80-100°C to obtain a uniform solution.

[0029] Add silver nitrate solution to the homogeneous solution to obtain a hot solution.

[0030] Weigh ascorbic acid and dissolve it in ultrapure water to obtain ascorbic acid solution.

[0031] Add the ascorbic acid solution into the hot solution, mix well, heat at 40-80°C for 3 minutes, and place at room temperature for 0.5 minutes-3 hours to form a uniform transparent light gray hydrogel.

Abstract

The invention discloses a preparation method for supermolecule hydrogel containing silver nanoparticles, and belongs to the technical field of nanometer materials. The preparation method for supermolecule hydrogel containing silver nanoparticles comprises the following steps that: dissolving a D type Fmoc-Phe gel factor in buffer solution of which the pH (Potential of Hydrogen) value is 7.4, and guaranteeing that the concentration of the D type Fmoc-Phe gel factor in first mixed solution is 6-20mg / mL; shocking the first mixed solution for 30s, and then, heating and dissolving at the temperature of 80-100DEG C to obtain even solution; adding silver nitrate solution into the even solution to obtain hot solution; weighing ascorbic acid, and adopting ultrapure water to dissolve to obtain ascorbic acid solution; and adding the ascorbic acid solution into the hot solution to form even and transparent grayish hydrogel. By use of the preparation method for the supermolecule hydrogel containingsilver nanoparticles, the silver nanoparticle can be subjected to in-situ preparation in the hydrogel, and silver nanoparticles are evenly dispersed, and perform a good growth suppression effect on gram positive bacteria which take staphylococcus aureus as a representative.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a method for preparing a supramolecular hydrogel containing silver nanoparticles Background technique [0002] In recent years, due to its good electrical conductivity and excellent optical and magnetic properties, silver nanomaterials have broad application prospects in nanoelectronic devices, biomedical engineering and other fields. There are many kinds of silver nanomaterials, such as silver nanoparticles, silver nanowires and so on. At present, there are many methods for preparing silver nanomaterials, such as vapor phase evaporation, sputtering, electrolysis, chemical reduction, photochemical precipitation and so on. [0003] Supramolecular hydrogels are a kind of colloids that are self-assembled by small molecules through non-covalent bond forces to form colloids similar to polymer materials, and are a kind of "soft matter". This kind of self-assembly exists widely ...
