Silver Nanoparticles in Medical Applications

Silver nanoparticles have emerged as one of the most common nano-materials used in the consumer market today. It comprises nearly 20% of all consumer products that contain nanotechnology. These nano-enabled commodities contain nanosilver particles that range from 10 nm to 100 nm in size. The nanoparticles are usually applied as a coating to products because the silver offers added antibacterial benefits. Although silver has long been hailed for its highly effective antibacterial properties, the consumer use of silver nanoparticles is controversial. This research focuses on the societal implications of silver nanoparticles for use in medical applications, such as the treatment of wounds or as a spray for surgical instruments and as a contraceptive. To carry out the research, product information was obtained through the examination of product literature from various sources. Additionally, a global value chain was constructed to provide a thorough product analysis. This investigative approach exposed the toxicity and environmental impact of silver nanoparticles as well as its health implications. Scientists and researchers have noted that silver is relatively safe and non-toxic to mammalian cells; however, silver in the bulk form versus the nanoscale may be disparate in their toxicity. In addition, long-term exposure studies, including organ accumulation, degradation, and possible adverse effects are limited and slowly understood. This research reviews the major questions concerned with increased use of silver nanoparticles in medical applications.
