"Noni Plant-Based Green Method for Producing Bactericidal Copper Oxide Nanoparticles"

Scientists have developed a green method for producing bactericidal copper oxide nanoparticles from the noni plant, Morinda citrifolia, which is common in Asia. The nanoparticles were obtained through a biological process using noni leaf extract and exhibited antibacterial and antifungal properties. The resulting nanoparticles, ranging in size from 20 to 50 nanometers, showed activity against various bacteria and fungi and have potential applications in biomedicine, fuel cells, batteries, and food storage, although further research is needed to minimize toxicity while maintaining their biological effectiveness.
