Nano silver is nano-scale metallic silver simple substance:
Nano-silver particles, spherical, 15-80nm diameter X-ray diffraction
Antibacterial research
Antibacterial test (Candida albicans)
For Candida albicans, normal saline, β-GP, and 0.1 mol / L acetic acid have no antibacterial effect, while CS, Ag-CS, Ag-CS / β-GP all have certain antibacterial effects, and with the gel The higher the silver content of the solution, the better the antibacterial effect.
Antibacterial test (Staphylococcus aureus)
For Staphylococcus aureus, normal saline, β-GP, and dilute acetic acid have no antibacterial effect, while CS, Ag-CS, Ag-CS / β-GP all have a certain antibacterial effect, and with the gel solution's The higher the silver content, the stronger the antibacterial effect.
The role and efficacy of nano silver
1. Strong penetrability, broad-spectrum sterilization and no drug resistance.
Nano-silver particles have strong permeability, can quickly penetrate into the subcutaneous 2mm sterilization, and are resistant to drug-resistant pathogens such as resistant E. coli, resistant Staphylococcus aureus, resistant Pseudomonas aeruginosa, Streptococcus pyogenes, resistant enterococci, anaerobic bacteria Multi-faceted antibacterial activity; it has bactericidal effect on bacteria common to burns and wounds such as Staphylococcus aureus, E. coli, Pseudomonas aeruginosa, Candida albicans and other Gram-positive and Gram-negative pathogens; It also has a strong bactericidal effect on Chlamydia trachomatis and gonococci that cause sexually transmitted diseases.
2. Repair and regeneration
Nano-silver can promote wound healing, promote the repair and regeneration of damaged cells, remove saprophytic muscle, antibacterial and anti-inflammatory to improve the microcirculation of tissues around the wound, effectively activate and promote the growth of tissue cells, accelerate wound healing, and reduce scar formation.
Nano silver performance advantages
1 Broad-spectrum sterilization without drug resistance;
2 Promote wound healing and repair;
3 Prolong antibacterial aging time by slow-release dispersing carrier;
4 Good dispersibility, uniform and stable dispersion, good stability;
5Good water solubility;
6 Good biocompatibility.
Application prospects
Biomedicine: gynecological disinfection, antibacterial dressings (wound stickers, burns and scald stickers), antibacterial lotions
Beauty and skin care: Acne, anti-inflammatory, high-end preservatives.
