The limitless possibilities of nanotechnology can be explained by the remarkable antimicrobial activity demonstrated by plant-derived biometallic nanoparticles, with a particular focus on their interactions with metal oxides. Plant-derived biomaterials and metal oxides work harmoniously to provide a new dimension in materials science that might lead to ground-breaking applications in environmental remediation and biomedicine. Using sophisticated analytical methods, including transmission electron microscopy, Fourier-transform infrared spectroscopy, and X-ray diffraction, this work consists of a systematic inquiry into the production and characterization of these biometallic nanoparticles. The results highlight the exact control over particle size, shape, and composition, highlighting how important these factors are in determining the resultant nanoparticles’ ability to fight microbes. One of the main themes involves antioxidant activity, as the biometallic nanoparticles made from plants have the natural capacity to scavenge free radicals, which enhances their antimicrobial effectiveness. The work carefully evaluates the processes behind this dual function, providing insight into the complex interactions between metal oxides and chemicals originating from plants. This study delves into possible uses in biological remediation, where the produced nanoparticles show promise in reducing environmental pollutants. It emphasizes how environmentally benign the suggested biometallic nanoparticles are, imagining a long-term strategy to mitigate microbial dangers and concurrently clean up contaminants in various ecosystems. An in-depth understanding of the complex interactions between biometallic nanoparticles generated from plants and metal oxides, as well as the various roles that these materials play in biological remediation and antimicrobial activity, is obtained. Thus, our review offers a paradigm change in the design and use of materials, opening up opportunities for further developments in nanotechnology.
