Embodiment 1

[0037] The steps of a preparation method of a titanium carbide-manganese sulfide composite antibacterial material are as follows:

[0038] (1) 30mg titanium carbide is dispersed in 30mL ultrapure water, is configured into solution I;

[0039] (2) adding solution I to 0.245g of manganese acetate tetrahydrate and stirring, and configuring solution II;

[0040] (3) Dissolve 0.121 g of L-cysteine ​​in 5 mL of ultrapure water to configure solution III;

[0041] (4) adding solution III to solution II and stirring for 1 h, and configuring solution IV;

[0042] (5) Transfer solution IV to the autoclave, and react at 200°C for 16h;

[0043] (6) After the solution was cooled, the collected precipitates were washed with ultrapure water and absolute ethanol for three times respectively, and then vacuum-dried at 80°C for 12 hours to obtain the titanium carbide-manganese sulfide composite antibacterial material.

[0044] from figure 1 and figure 2 It can be seen that the layered titan...

Abstract

A preparation method of the titanium carbide-manganese sulfide composite antibacterial material is an antibacterial method, and comprises the following steps: dissolving manganese acetate tetrahydrate in a titanium carbide dispersion liquid, adding an L-cysteine solution, uniformly stirring, carrying out a hydrothermal reaction, carrying out centrifugal separation on a precipitate, and drying to obtain a titanium carbide-manganese sulfide composite. The material is uniformly dispersed in sterile water, a titanium carbide-manganese sulfide composite material with a certain concentration is respectively placed in EP tubes of escherichia coli and staphylococcus aureus, 808nm near-infrared laser is selected to irradiate the composite material, and the survival rate of bacteria is analyzed after the composite material is placed in an incubator overnight. Titanium carbide is added to efficiently inhibit bacteria by using the excellent photo-thermal performance of titanium carbide, and meanwhile, the dispersing performance of titanium carbide in water is utilized; the prepared composite material has better photo-thermal conversion efficiency, further obtains better antibacterial performance, and has a good inhibition effect on gram negative bacteria and gram positive bacteria.

Description

technical field [0001] The invention relates to the technical field of bacteriostasis, in particular to a titanium carbide-manganese sulfide composite bacteriostatic material, a preparation method and a bacteriostatic method thereof. Background technique [0002] In recent years, infectious diseases caused by bacteria have continued to increase and have become one of the major problems threatening human health worldwide. Many traditional anti-infective treatments that rely on antibiotics have gradually lost their effectiveness due to the emergence of drug-resistant strains. Therefore, the development of new antibacterial agents is particularly important. Among them, new antibacterial therapies based on nanomaterials have received more and more attention, such as photothermal therapy (PTT), photodynamic therapy (PDT) and ultrasound therapy. Among these therapies, ROS-based antimicrobial therapy has higher efficacy and fewer side effects. Studies have shown that high concen...
