Research on zinc oxide (ZnO) has surged in recent years due to its extensive range of applications because its unique physical and chemical properties make it ideal for various uses, including acoustic devices, photocatalysis, pharmaceuticals, light-emitting diodes, solar cells and antibacterial agents. ZnO nanoparticles are particularly notable for their biocompatibility, low toxicity and stability, making them suitable for drug delivery and antiviral applications. The versatility of ZnO has led to a proliferation of scientific publications, prompting a need for comprehensive reviews to synthesize current knowledge and highlight potential future applications. This review focuses on the latest advancements in ZnO research, emphasizing its applications when doped with noble and transition metals. Doping ZnO nanoparticles enhance their properties, such as magnetic, electrical and antimicrobial characteristics, thereby expanding their functionality. Studies have demonstrated that doping ZnO with metals like copper (Cu), iron (Fe), cobalt (Co) and tin (Sn) can significantly improve their performance in various fields, from targeted drug delivery and magnetic hyperthermia to enhanced conductivity and antimicrobial activity. These findings underscore dopingās critical role in optimizing ZnOās properties for diverse high-impact applications.
