Nano-molybdenum sulfide antibacterial material and synthetic method thereof and application thereof

Abstract

The invention discloses a nano-molybdenum sulfide antibacterial material and a synthetic method thereof and application thereof. The synthetic method comprises the following steps: (1) dissolving polyethylene glycol solid in water, performing ultrasonic processing in an ultrasonic pool until the polyethylene glycol is dissolved completely, adding ammonium heptamolybdate solid, and performing ultrasonic processing until the ammonium heptamolybdate is dissolved completely to obtain a mixed solution; and (2) dissolving thiourea solid in water, dissolving the thiourea with stirring, adding the dissolved thiourea into the mixed solution, stirring the mixture, putting the mixture into a hydrothermal reactor having a polytetrafluoroethylene inner container, sealing the reactor, and performing heating reaction to obtain a black precipitate which is the nano-molybdenum sulfide antibacterial material. The invention also provides the nano-molybdenum sulfide antibacterial material which is prepared by the synthetic method. The invention also provides application of the nano-molybdenum sulfide antibacterial material on synergistic anti-microbial combining biomimetic catalysis hydrogen peroxide and near-infrared optothermal. The nano-molybdenum sulfide antibacterial material prepared by the synthetic method in the invention has high yield, and can be captured easily by bacteria. Moreover, the antibacterial effect of the material is obviously better than that of single biomimetic catalysis anti-microbial or single near-infrared optothermal anti-microbial.

Description

technical field [0001] The invention relates to the field of antibacterial material preparation, in particular to a nanometer molybdenum sulfide antibacterial material and its synthesis method and application. Background technique [0002] Inflammatory diseases caused by bacteria have seriously endangered human health. The advent of clinically used antibiotics for antibacterial and anti-inflammation has saved many patients with bacterial infections. However, whether natural or synthetic antibiotics are used or abused for a long time In the process, the problem of bacterial drug resistance will become more and more serious. At the same time, the abuse of artificially synthesized antibiotics may also cause serious environmental pollution. Although natural antibiotics are less toxic and polluted, the processing and synthesis conditions are harsh, which is not conducive to large-scale industrialization. Thereby limiting its application in the medical field. [0003] The rapid d...

Problems solved by technology

[0007] in MoS 2 Among the several main synthesis methods of nanosheets, most of the methods obtain sheet products with low yields and sizes on the order of microns, which are not easy to be phagocytized by cells or effectively captured by bacteria.

The synthesis process of n-butyllithium intercalation method, which is widely used, must be carried out in a vacuum glove box. The intercalation time is long and hydrogen is generated, and the size of nanosheets is not easy to control.
