Silver Nanoparticles: Insights into Their Physiochemical, Optical, and Electrical Properties a Review
摘要
Nanoparticles are substances that are of immense advantage due to their exquisite surface-to-volume ratio. Among them, silver nanoparticles are one of the most notable classes of metallic nanoparticles, which have a wide range of applications in biomedical aspects, material fabrication, and other uses. They are synthesized by both top-down and bottom-up approaches. Yet sustainable methods of silver nanoparticle synthesis are currently being explored using a wide arena of eco-friendly sources. The properties of silver nanoparticles vary deeply in comparison with their macro forms. They possess unique and peculiar properties like strong absorption of photons and increased thermal and electrical conductivity and are capable of being modified into different shapes and various sizes and could be fabricated into many nano-objects. Silver nanoparticles also have many notable pharmacological properties, like anti-cancerous, anti-inflammatory, anti-microbial, anti-oxidative, and anti-angiogenic nature. In addition to this, they are deployed for various other applications like wastewater treatment, biosensing, imaging, cosmetics, and drug delivery. This review briefly describes the conventional and sustainable synthesis strategies, optical properties, physiochemical properties, and electrical properties of the silver nanoparticles along with their application in various fields.
