In the last two decades, the arena of nanotechnology has emerged as one of the generation revolutionizing every field of applied sciences. This paper therefore examines the outcomes of silver and zinc oxide nanoparticles and their programs in biological system. Nanoparticles (NPs) had been discovered to show some exclusive particles due to their excessive small length and really high surface area to volume ratio that have been attributed to vast variations inside the properties over their big equivalents. Zinc oxide nanoparticles (ZnO NPs), are taken into consideration as one the maximum important metal oxide nanoparticles that are significantly applied in numerous fields as a result of their often chemical and physical properties. Zinc oxide nano particles (ZnO NPs) because of its small size is now used in biomedicine, optics, electronics, and agriculture. Silver Nanoparticles (Ag NP) is an antimicrobial agent to wide range of bacteria species inclusive of kitchen microbe along with E. Coli. Findings display that silver and zinc oxide nanoparticles are useful agents for anticancer, antibacterial and anti inflammatory. ZnO and Ag NPs has been documented to have effect in several biological device weighing its sustainability measures to be stepped forward; Anticancer: most cancers that is a circumstance of uncontrolled malignant of cell proliferation has usually been handled via the use of radiotherapy, chemotherapy and surgical operation for many years now.

Antibacterial Activity: ZnO and Ag NPs are also used as an antibacterial material owing to its superior properties that includes high activity to block a wide scope of pathogenic agents and high specific surface area. Reports indicate that the antibacterial toxicity mechanism of ZnO NPs is based on its ability to induce excess ROS generation, such as hydroxyl radicals, superoxide anion, and hydrogen peroxide production.

Silver Nanoparticles and its packages Silver Nanoparticles (Ag NP) is an antimicrobial agent to big selection of bacteria species with latest technological advances which has helped in the reduction of silver compound to nanoscale sized particles hence enabling the combination of this very important antimicrobial into a larger quantity of substances— such as coatings, plastics and foams (natural and artificial fibers). Silver in Nano-sized shape offer more long lasting antimicrobial protection that is often during the existence of the product. Recent researches in inorganic nanomaterials with suitable antimicrobial homes have opened a new technology in scientific and pharmaceutical industries.Silver nanoparticles have recently shown as a promising antimicrobial agent which acts on a wide range of target sites whether extracellularly or intracellarly. In Anti-Inflammatory Activity: The advent of nanoparticles with the biological activities of zinc ions has made it an agent of anti-inflammatory. Chronic inflammatory skin disease such as Atopic dermatitis (AD) which is characterized by the impairment of the skin-barrier functions is presently been treated using ZnO NPs..

Of new, ample facts has been provided on antimicrobial outcomes of Zinc Oxide and Silver Nanoparticles within the biological system. Numerous research achieved have proven that despite been a novel approach towards medicine, nanoparticles such as Zinc Oxide and Silver Nanoparticles are increasingly receiving attention owing to their properties and chemical compositions. Their applications in wide range of chemical and biological activities have made

them one of the promising breakthroughs in medical and technological sciences. Therefore more research needs to be done to explore the various ways Zinc Oxide and Silver Nanoparticles can remain useful agents for technological development and growth in medicine sub-sector.
