Activity of Silver Nanoparticles

Nanotechnology has emerged as a dynamically developing area of scientific interest in the world. Nanoparticles are defined as a Nano scale particle of size ranging from 1 to 100 nm. Among the metallic nanoparticles, silver nanoparticles (AgNPs) have gained increasingly attention due to its unique physical, biological and chemical properties. AgNPs are well-known to exhibit a strong antimicrobial activity against various microorganisms such as bacteria, viruses, and fungi due to its smaller in size and large surface area. AgNPs are also widely used as anti-inflammatory and anti-viral properties.

Development of multidrug resistance among pathogens has become a global problem for chemotherapy of bacterial infections. Extended-spectrum β-lactamase- (ESβL-) producing enteric bacteria and methicillin-resistant Staphylococcus aureus (MRSA) are the two major groups of problematic MDR bacteria that have evolved rapidly in the recent past. The nanoparticles were predominantly found to be spheroidal with particle size distribution in the range of 5–20 nm.

The antibacterial activity of AgNPs has been reported by many researchers. However, the MIC values from the previous studies showed the range through a large extent of variation. Therefore, the comparison of the results is difficult as there is no standard method for determination of antibacterial activity of AgNPs and different methods have been applied by the researchers.

silver (Ag) NPs are particularly outstanding because of their potential applications in health care,textile fibers,food packaging,and antibacterial fields.Moreover, Ag-NPs are considered non-toxic or less harmful to mammalian tissues and environmentally friendly when used in relatively low concentrations at the same size and shape.In recent years, extensive interrelated investigations have been performed to better utilize Ag-NPs for the inhibition of bacteria, however, there is an ongoing debate regarding the antibacterial mechanism of action of Ag-NPs. In previous studies, it has been indicated that the bactericidal properties of Ag-NPs primarily depend on the release of Ag+ ions from NP surfaces, followed by the interaction of Ag+ ions with cellular targets.
