Biosynthesized Silver Nanoparticles for Diagnostics

Nilesh S. Paul

Biosynthesized silver nanoparticles represent a cutting-edge advancement in the field of diagnostics, offering a versatile and eco-friendly approach for the development of highly sensitive and cost-effective diagnostic tools. These nanoparticles are produced through the reduction of silver ions using natural sources, such as plant extracts, microorganisms, or biomolecules, which act as reducing and stabilizing agents. This green synthesis method not only minimizes the environmental impact associated with traditional chemical methods but also harnesses the unique properties of silver nanoparticles for a wide range of diagnostic applications. One of the key advantages of biosynthesized silver nanoparticles is their exceptional tunability in terms of size, shape, and surface chemistry. This tunability allows for precise tailoring of their properties to meet the specific requirements of various diagnostic assays. Silver nanoparticles exhibit strong localized surface plasmon resonance (LSPR) in the visible and near-infrared range, resulting in distinct color changes that are easily detectable with the naked eye or a simple UV-visible spectrophotometer. This colorimetric response is widely used for ualitative and semi-quantitative assays, such as point-of-care testing for diseases like malaria and HIV. Furthermore, the high surface area of silver nanoparticles enhances their ability to immobilize biomolecules, such as antibodies, antigens, or DNA probes, making them valuable tools for the development of biosensors. These biosensors can detect target analytes, including pathogens, biomarkers, or environmental pollutants, with remarkable sensitivity and specificity. The interaction between the immobilized biomolecules and the analyte induces changes in the LSPR properties, leading to measurable signals that can be quantified using simple optical or electrochemical techniques. This technology has been applied in the rapid detection of various diseases, including COVID-19, as well as in environmental monitoring.
