What Are the Types of Nanoparticles Used for Antibacterial Purposes?
Several types of nanoparticles exhibit superior antibacterial properties:
1. Metallic Nanoparticles: Silver, gold, and copper nanoparticles are well-known for their potent antibacterial effects. Silver nanoparticles, in particular, have been widely studied and used for their broad-spectrum activity. 2. Metal Oxide Nanoparticles: Nanoparticles like zinc oxide and titanium dioxide are effective in producing ROS, leading to bacterial cell death. 3. Carbon-Based Nanomaterials: Graphene oxide, carbon nanotubes, and fullerenes have shown promising antibacterial properties due to their physical and chemical interactions with bacterial cells. 4. Polymeric Nanoparticles: These can be engineered to carry and release antibacterial agents in a controlled manner, targeting specific bacterial infections.
