Article Title: Biogenic copper and copper oxide nanoparticles to combat multidrug-resistant Staphylococcus aureus : Green synthesis, mechanisms, resistance, and future perspectives

doi: 10.1016/j.btre.2025.e00896

Figure Lengend Snippet: Synthesis methods of copper and copper oxide nanoparticles. Classification of synthesis methods into Top-Down (physical, toxic) and Bottom-Up (chemical, toxic; biological, non-toxic) approaches. Physical methods involve breaking bulk materials into nanoparticles, while chemical and biological methods build nanoparticles from molecular precursors. Biological methods offer a green alternative using plant extracts, algae, fungi, and bacteria.
