This invention discloses a polymer-loaded drug-eluting nanoparticle with high encapsulation efficiency and its application in coatings and surface film materials. The polymer-loaded drug-eluting nanoparticles are prepared via emulsion polymerization, simultaneously loading antibacterial drugs with different log P values. The preparation process is simple, and the resulting product has small particle size, high molecular weight, high uniformity, and high drug encapsulation efficiency, achieving the substitution of non-reactive surfactants with reactive surfactants. A coating can be prepared using the above-mentioned polymer-loaded drug-eluting nanoparticles. The coating can be further used to prepare sustained-release antibacterial surface film materials through cross-linking film formation, exhibiting good mechanical properties, excellent chemical resistance, and high safety. This invention can be widely applied to various environmental and material surfaces, including but not limited to surface modification of instruments and building materials in residential and medical environments, thereby achieving a long-lasting antibacterial effect.

Despite the existence and deployment of a range of antimicrobial / disinfectant / sterilization technologies and products, transmission of infectious diseases remains a significant problem worldwide, continuing to cause hundreds of millions of infections and millions of deaths every year of both human beings and animals. State-of-the-art technologies suffer from several disadvantages including being discrete in space and time, being overly dependent on human skill and discipline, and in some cases having harmful side-effects to human health. This invention proposes a series of industrial grade antimicrobial product designs, and materials and methods to make them highly effective products that offer continuous antimicrobial action, with minimum dependence on human discipline and skill once deployed, and with no harmful side-effects. Methods may include either or both first and second materials be formed by vapor or solution-based coating schemes and many may be antimicrobial in nature. Nanopores and / or nanotubes produce an ultra-high anti-microbially active surface area.

The present invention is directed to an antimicrobial substrate having a layer of PbTe quantum dots (QD) attached to an outer surface of the material. Further provided is a method of fabrication the substrate / modification of a material for obtaining an antimicrobial surface.

The application discloses a cassava tuber postharvest browning inhibition and fresh storage quality preservation treatment method, which comprises a three-step synergistic process of polyphenol oxidase targeted inhibition pretreatment, selective air permeable composite coating treatment and biological antagonistic bacteria surface inoculation treatment. First, the tuber is immersed in a vacuum infiltration treatment of a citric acid and L-cysteine hydrochloride composite inhibition solution, then is immersed and coated with a chitosan-sodium alginate-nano silicon dioxide selective air permeable composite coating, and finally is sprayed with bacillus subtilis inoculation. The three-step treatment synergistically realizes vascular browning inhibition for 25-30 days, and prolongs the shelf life from 2-3 days to 3-4 weeks.

The present development is an antimicrobial surface nanostructured carbon-based coating for a substrate, a process for making the antimicrobial surface coating, and a method for using the coating to inhibit pathogen growth on the substrate surface. The carbon-based coating material comprises pure carbon deposited on the substrate as a plurality of elongated nanostructures wherein each nanostructure has a high aspect ratio. The high aspect ratio creates needle-like nanostructures on the surface that exhibit antimicrobial properties. In an exemplary embodiment, the carbon-based coating is a diamond coating wherein the elongated nanostructures have a needle-like morphology and each needle has a height of <5 μm and an extremely sharp radius of curvature at the tip.
