Abstract/Executive Summary
Over the years, the field of nanotechnology has been widely focused on and continuously evolving. A part of this would be the production of nanoparticles, which can be physically and chemically produced. Despite this, commercially producing nanoparticles negatively impacts the environment due to their potential toxicity, which can be associated with their physical and chemical production methods. Because of this, alternatives were made, such as using green synthesis methods like biosynthesis, which involves using plant extracts to produce and develop nanoparticles. Copper oxide nanoparticles (CuONP) are widely used metallic nanoparticles. However, the usual production methods of these CuONPs are costly and hazardous, leading to an alternative, which is plant-mediated synthesis or simply biosynthesizing CuONPs through plant extracts, such as the Kamias (Averrhoa bilimbi) fruit extract, to act as the reducing agent for the precursor solution. This study will emphasize the need for a more environmentally sustainable alternative for nanoparticle production due to the usual methods bearing potential toxicity. It may negatively impact humans and the environment while addressing public health concerns.
