Introduction to Nano Silver Nano Silver refers to silver particles with dimensions typically between 1 and 100 nanometers . At this nanoscale, silver exhibits significantly enhanced properties compared to bulk silver, including strong antimicrobial activity, high surface reactivity, and excellent electrical conductivity . Due to these unique characteristics, nano silver has become an important functional material in modern industry, with applications spanning healthcare, electronics, textiles, environmental protection, and advanced materials. Physical and Chemical Properties of Nano Silver The performance of nano silver is closely related to its particle size, morphology, and surface treatment. Key properties include: Extremely small particle size , resulting in a high surface-area-to-volume ratio Strong antimicrobial efficiency at low concentrations High electrical and thermal conductivity Surface tunability , allowing improved dispersion and stability Chemical activity , ...
