Exploratory advancement in the optimal utilization of bio-wastes for ZnO nanoparticle synthesis in antimicrobial applications

The wealth out of Waste (WoW) concept progressively developed for the industrial revolution in recent years. So, bio-waste mediated synthesis of nanoparticles has emerged as a promising approach, leveraging the unique properties of bio-wastes and agricultural wastes. In this study, extracts from Eggshell, Peanut husk, and Orange peels were used to synthesize zinc oxide nanoparticles. The structural, vibration, and morphological properties of the synthesized ZnO nanoparticles were investigated and reported. It reveals that the distinct vibration peaks with strong existence of Zn-O bands from FT-IR spectra. Overall, this study highlights the incomparable structural and morphological properties of bio-waste extracts and their impact on the synthesis and functionality of zinc oxide nanoparticles, paving the way for future research in antimicrobial and targeted drug delivery applications.
