Waste to Value: Synthesis and Microbial Evaluation of Silver Nanoparticles from Eggshells

The development and application of materials whose components are located in the nanometer, usually up to 100 nm is referred to as nanotechnology. This study examines sustainable synthesis of silver nanoparticles using egg shells as a new biologically reducing and stabilization agent. The amount of calcium carbonate and other organic ingredients in egg shells provide cost -effective and ecological alternative to conventional methods of chemical synthesis synthesis. The nanoparticles were synthesized by a green approach, probably including a reduction in silver ions (AG+) with an egg extract. The produced nanoparticles were analysed using several characterization techniques, including UV- spectroscopy, dynamic light scattering (DLS), scanning electron microscopy (SEM). Transmission electron microscopy (TEM) was used to assess the size and shape of the particles, and X -ray diffraction (XRD) could be used to examine the crystalline structure. Antimicrobial efficacy of synthesized nanoparticles has been tested against the selection of bacterial and/or fungal strains by established methods such as test diffusion agar or determination of minimum inhibitory concentration (MIC). This research emphasizes the ability to use Biowaste to create valuable nanomaterials that can be applied in many areas such as medicine, agriculture and environmental cleaning.
