Annotation

In recent years, the method of synthesizing materials with limited use of chemicals has attracted the attention of many researchers. Nano zinc oxide, an object with potential in biomedical applications, has also been synthesized by this method. In this study, ZnO NPs were prepared by a very simple green synthesis method using zinc acetate hexahydrate and using guava leaf extract which acted as capping agents without using any additional chemicals. any. Zinc oxide nanoparticles synthesized by this pathway (GL-ZnO) have been described by X-ray, EDX, FTIR, and SEM techniques. The results show that GL-ZnO has high purity, uniform size, and fineness at the nanoscale. The influence of synthesis conditions on the characteristics of ZnO NPs was evaluated. The IR, and EDX results demonstrate the formation of ZnO NPs, while the SEM results show the size of ZnO at the nanoscale. ZnO NPs showed good antibacterial activity against several gram-negative and gram-positive strains such as E. coli, B. subtilis, and S. cerevisiae
