Nanoparticles and Their Applications: A Comprehensive Review

Nanoparticles (NPs), defined as particles with at least one dimension between 1 and 100 nanometers, have garnered significant attention due to their unique physicochemical properties, which differ markedly from their bulk counterparts. These properties include high surface area-to-volume ratio, quantum effects, and the ability to functionalize their surfaces. This review delves into the synthesis methods of nanoparticles, their diverse applications across various fields such as medicine, environmental science, agriculture, and electronics, and the challenges and future prospects associated with their use.
