Synthesis of ZnO nanoparticles are done by using an innovative technique of chemical synthesis (co-precipitate technique). In this technique ZnO-NPs and Capped ZnO-NPs with glucose are produced by adding NaOH solution drop by drop on continuous magnetic stirring. by dissolving a precise quantity of zinc nitrate hexahydrate (Zn (NO3)2·6H2O) in distilled water to create a transparent solution. Subsequently, transfer the nitrate solution into a reaction vessel. While continuously stirring with a magnetic stirrer, gradually add NaOH solution drop by drop. This process should result in the formation of a white precipitate of ZnO, with continuous stirring ensuring thorough precipitation. To regulate particle size and enhance stability, introduce glucose into the reaction mixture as a capping agent, utilizing a magnetic stirrer to facilitate proper capping and stabilization of ZnO-NPs. Separate the ZnO-NPs from the solution by centrifuging the reaction mixture, followed by the collection of the precipitates. Subsequently, wash the obtained ZnO-NPs with distilled water to eliminate impurities. Dry the washed ZnO-NPs in an oven at a specified temperature to eliminate any residual impurities. Characterization of these particles were done by using confirmatory techniques like UV-Visible Spectroscopy, Photoluminescence Spectroscopy, Particle size analyzer, Zeta potential, Fourier transform Infrared radiations spectroscopy (FTIR Spectroscopy) and scanned electron microscopy (SEM). There are two different applications against which nanoparticles are added. 1st is Fingerprint enhancement and the 2nd is Antimicrobial activity. ZnO-NPs Provide very effective results against finger print analysis on both smooth and rough surfaces. Antimicrobial activity is studied under two different bacteria one is gram +ve S. auras and the other is gram –ve E. coli. S. auras show sensitivity with ZnO-NPs while E. coli didn’t.
