Biosintesis Dan Karaterisasi Nanopartikel Zno Menggunakan Ekstrak Daun Sirih …

Bacterial resistance to antibiotics has become a global challenge, prompting the search for more effective and environmentally friendly antibacterial alternatives. This study aims to synthesize and characterize zinc oxide (ZnO) nanoparticles using a biosynthesis method with green betel leaf (Piper betel L.) extract as a reducing and stabilizing agent. The synthesis process was carried out by mi…
