Development of Narrow Size Distribution Silver Nanoparticles as Standard Reference Material/Bhartiya Nideshak Dravay for TEM/HRTEM and Particle Size Analyzer Instruments

Silver nanoparticles (Ag NPs) with narrow size distribution were derived chemically by sol–gel process and characterized XRD, high resolution transmission electron microscopy (HRTEM) techniques to confirm their formation, morphology, particle properties. The variation in of as prepared Ag NPs monitored periodically every month HRTEM for the last six months check stability time assign shelf life Bhartiya Nideshak Dravay (BND) estimated overall expanded uncertainty nanoparticles. traceability developed silver will be from NIST standard reference material or other NMI which established facility assigning size. Such BNDs different sizes can used calibration instruments like TEM/HRTEM analyzers research find usage many industrial applications global acceptance.
