What are Antibacterial Nanopowder/Nanoparticles?

Antibacterial nanopowders or nanoparticles are ultrafine materials engineered at the nanoscale to exhibit strong antibacterial properties. These nanoparticles, commonly composed of silver (Ag), zinc oxide (ZnO), copper oxide (CuO), or titanium dioxide (TiO₂), effectively inhibit bacterial growth, making them ideal for medical, textile, cosmetic, and industrial applications.

Chemical Properties and CAS Numbers

• Common Antibacterial Nanoparticles:
  • Silver nanoparticles (Ag): CAS 7440-22-4
  • Zinc oxide nanoparticles (ZnO): CAS 1314-13-2
  • Copper oxide nanoparticles (CuO): CAS 1317-38-0
  • Titanium dioxide nanoparticles (TiO₂): CAS 13463-67-7
• Appearance: Fine powders, typically white or metallic grey
• Solubility: Varies; typically insoluble in water
• Stability: Chemically stable under standard conditions
• Mode of Action: Disrupt bacterial cell membranes, generate reactive oxygen species, and interfere with bacterial DNA replication

Applications of Antibacterial Nanopowder

1. Medical and Healthcare

Used in wound dressings, medical implants, surgical instruments, and antibacterial coatings to reduce infection rates and promote faster healing.

2. Textiles and Fabrics

Integrated into clothing, bedding, masks, and hospital linens to inhibit bacterial growth, reduce odors, and enhance hygiene.

3. Personal Care and Cosmetics

Employed in deodorants, lotions, soaps, and skincare products for antibacterial protection and improved shelf-life.

4. Food Packaging

Incorporated into packaging materials to prevent bacterial contamination, extending shelf-life and ensuring food safety.

5. Water Treatment

Applied in water filtration systems and purification processes, effectively eliminating harmful microorganisms and enhancing water quality.

6. Electronics and Consumer Products

Used in consumer electronics, appliances, and coatings to maintain hygiene by reducing bacterial growth on surfaces frequently touched.
