TYPES OF NANOPARTICLES
TYPES OF NANOPARTICLES Nanoparticles are tiny particles with dimensions in the nanometer range (1 to 100 nanometers). They possess unique properties that make them valuable in various fields, including medicine, electronics, and materials science. Here are the main types of nanoparticles: 1. Metallic Nanoparticles Gold Nanoparticles (AuNPs): Used in medical imaging, drug delivery, and cancer treatment due to their biocompatibility and ease of functionalization. Silver Nanoparticles (AgNPs): Known for their antimicrobial properties, commonly used in wound dressings and coatings. Platinum Nanoparticles: Employed in catalysis and as drug delivery agents. 2. Oxide Nanoparticles Titanium Dioxide (TiO₂) Nanoparticles: Used in sunscreen, photocatalysis, and as a white pigment. Zinc Oxide (ZnO) Nanoparticles: Applied in cosmetics, sunscreens, and antimicrobial coatings. Iron Oxide Nanoparticles: Utilized in magnetic resonance imaging (MRI) and as drug delivery vehicles. 3.
