2results about How to "Efficient antibacterial effect" patented technology

The preparation method of the ultrasonic trigger azide prodrug selective activation targeted antibacterial preparation of the application belongs to the field of biological medicine and nanomaterials. First, Mal-PEG-PDLLA and HHC-10 are coupled through a thiol-maleimide reaction, dialysis, and freeze-drying to obtain an antibacterial peptide modified carrier HPP; then SMX-N3, TBR, and the antibacterial peptide modified carrier HPP are dissolved in dichloromethane to form a uniform solution, and the organic solvent is evaporated to form a uniform film; finally, deionized water is added for hydration to self-assemble into nanoparticles; after filtration and freeze-drying, the target nano-preparation is obtained. The prodrug nano-delivery system prepared by the application has the advantages of controllable activation, efficient bacteriostasis, good biocompatibility, etc.

The utility model discloses a bacteriostatic air filter element module, which comprises a wave-shaped filter screen and a frame, a support belt is connected between adjacent folding surfaces of the wave-shaped filter screen, the support belt is positioned on the air outlet side of the wave-shaped filter screen, a bacteriostatic module is arranged in a space formed by the support belt and the folding surfaces, and the bacteriostatic module is connected with the frame. The antibacterial module comprises a module shell, and the module shell is filled with antibacterial volatile matter. According to the utility model, the bacteriostatic action of the air filter element on air is realized, and meanwhile, the influence on air flow is small.
