Silver nanoparticles are tiny particles of silver that measure between 1 and 100 nanometers in size. Due to their small size, they exhibit unique physical and chemical properties, making them useful in various applications, including medicine, electronics, and environmental protection. They are known for their antibacterial properties, which help in preventing infections and promoting healing. These nanoparticles can be synthesized through various methods, including chemical reduction and green synthesis using plant extracts. Their effectiveness in applications such as antimicrobial coatings, drug delivery, and water purification has made them a focus of research in nanotechnology and materials science.
