An Effective Antimicrobial Effect by Silver Doped Zinc Oxide Nanoparticles Prepared by Co-precipitation Method Large-scale uses of nanosized amorphous silica particles can be found in a variety of common consumer goods, such as optical fibers, catalyst supports, non-diary coffee creamers, and car tires.Metallic nanopowders for magnetic recording tapes were created in the 1960s and 1970s, Granqvist and Buhrman released the first publication of micro crystals made using the now-famous inert-gas evaporation method in 1976 [1].It was discovered that Maya blue paint is a hybrid substance with nanostructures.Studies of genuine samples from Jaina Island reveal that the material is composed of needle-shaped palygorskite (clay) crystals that form a super lattice with a period of 1.4 nm, with intercalates of amorphous silicate substrate containing inclusions of metal (Mg) nanoparticles.The origin of the material's color and resistance to acids and biocorrosion are still unknown.The creation of synthetic samples has demonstrated that the presence of both these nanoparticles and the super lattice is necessary to get the lovely blue tone.Nanomaterials are incredibly small, with a minimum dimension of 100 nm or less.One dimension (such as surface coatings), two dimensions (such as strands or fibers), or three dimensions (such as particles) can all be considered nanoscale for nanomaterials.Additionally, it is possible to create nanocomposites for a variety of technological applications by choosing a polymer with specific favorable properties, such as conductivity, ABSTRACT: In the present work nanoparticles of silver (Ag) doped zinc oxide(ZnO) were successfully synthesized by the Co-precipitation method using zinc sulphate and polyvinylpyrrolidone (PVP) as the precursor materials.Ethylene glycol (EG) and (NaOH + Na2CO3) were used for the homogeneity and to maintain the pH value of the solution.It helps to make a stoichiometric solution of silver-doped zinc oxide nanoparticles.The samples were characterized by XRD, FTIR, DRS-UV, and FE-SEM with EDX.Antimicrobial activity was also studied for the synthesized material.XRD results show that the calcination temperature significantly affected the average particle size which indicates that undoped and Ag-doped ZnO crystals are in a hexagonal wurtzite structure.The antibacterial activity of the prepared samples was reported against pathogenic organisms like Escherichia coli, Pseudomonas, Staphylococcus aureus, (Gram-positive and Gram-negative bacteria) and for fungus Aspergillus, Candida, and Mucorsps, for all the compounds.These nanoparticles which have antimicrobial properties can be used in food preservation packing materials.
