Silver nanoparticles dispersion exhibit size and shape-dependent properties that are of interest for applications ranging from catalysis and sensing to optics, antibacterial activity, and data storage. The catalytic activity of silver nanoparticles is also dependent on their size as well as their structure, shape, size distribution, and chemical-physical environment. Additionally, owning to their broad-spectrum antimicrobial ability, silver nanoparticles have also become the most widely used sterilizing nanomaterials in consuming and medical products, for instance, textiles, food storage bags, refrigerator surfaces, and personal care products.

Silver nanoparticles dispersion: Medical professionals are putting silver nanoparticle solutions to the test to see how well they work against mouth infections caused by fungal infections. Yeast infections caused by Candida albicans and Candida glabrata readily thrive in the mouths of denture wearers, causing thrush and dental stomatitis -a painful infection that affects around 70 percent of denture wearers. These hard-to-treat mouth infections harbor microorganisms that quickly form biofilms. Antibiotics do nothing to kill these fungal growths and may actually contribute to them.

Silver nanoparticles (AgNPs) dispersion has been emerged as antimicrobial agents due to their high surface area to volume ratio and the unique physiochemical properties. Although the antibacterial mechanism of AgNPs is not fully understood, currently the great parts of the applications of AgNPs are in antibacterial and antifungal agents. In spite of their high antibacterial activity, AgNPs is highly reactive and easily susceptible to aggregation into large particles due to their high surface energy of AgNPs, resulting in deterioration of their unique chemical properties and a loss of their antibacterial activities.

Silver nanoparticles dispersion: Due to their unique properties, AgNPs dispersion has been used extensively in house-hold utensils, the health care industry, and in food storage, environmental, and biomedical applications. Several reviews and book chapters have been dedicated to various areas of the application of AgNPs. Herein, so nanoshel in emphasizing the applications of AgNPs in various biological and biomedical applications, such as antibacterial, antifungal, antiviral, anti-inflammatory, anti-cancer, and anti-angiogenic.

Silver nanoparticles dispersions possess wondrous optical, electronic, magnetic, and catalytic properties than the bulk material owing to their high surface area to volume ratio. Metal nanoparticles like silver show different colors due to their Surface Plasmon Resonance (SPR) phenomenon. It is a collective oscillation of free electrons of the metal nanoparticles in resonance with the frequency of the light wave interactions causing the SPR band to appear in the visible and infrared region
