Biosynthesis of zinc oxide nanoparticles by using fruits extracts of Ananas Comosus and its antibacterial activity

Abstract

Biosynthesis of metallic nanoparticles using plants, enzymes, and microorganism have been known as eco-friendly alternatives to conventional physical and chemical methods. Recently, the biological synthesis of nanoparticles has been a keen interest amongst researchers and scientist due to its simple technique, eco-friendliness, non-toxic, inexpensive and potential to perform in antibacterial activity. Thus, in this current work, the synthesis of zinc oxide (ZnO) nanoparticles using reduction agent from fruit extracts of Ananas Comosus is reported. The biosynthesized zinc oxide was characterized using Field Emission Scanning Electron Microscope (FESEM) with Energy Dispersive X-ray analysis (EDX), UV-Vis absorption spectroscopy and X-ray diffraction (XRD). The average size of the nanoparticles was found to be in the range of 30-57nm. The antibacterial activity of ZnO nanoparticles was carried out via agar diffusion method against pathogenic organisms. It is observed that the biosynthesized ZnO in the process has the efficient antibacterial activity. In conclusion, the green synthesis of zinc oxide nanoparticles using the fruit extract of Ananas Comosus is considered as a potential additive to substitute other metal oxides such as silver (Ag) and titanium dioxide (TiO2)but also provide antibacterial effect that able to enhance the nanoparticle performance.

Synthesis and Characterization of Chrysophyllum albidum (African Star Apple) Plant‐Mediated Zinc Oxide Nanostructures and Evaluation of Their Antioxidant, Anti‐Inflammatory, and Antimicrobial Activity

“…This clearly shows that samples synthesized from the seed were of the least particle size as compared to the leaf extract which gave a larger particle size. A similar morphology was reported by Ahmad et al [50] using fruit extract of Ananas comosus. This result is almost similar to ZnO NPs synthesized using P. granatum reported by Sukri et al [51].…”

Biosynthesis and Optimization of ZnO Nanoparticles Using Ocimum lamifolium Leaf Extract for Electrochemical Sensor and Antibacterial Activity

“…Recently, green synthesis of ZnO NPs has gained much attention in nanoscience and nanoengineering technology due to their cost-effectiveness, reliability, environmental friendliness, and use of cheap instruments during their synthesis. − Principally, different sources of plants and their various components produce active natural molecules like phenols, flavonoid polyphenolics, and alkaloids that can act as a good reducing and stabilizing agents for efficient ZnO NP preparation. − Previously, different plants, such as Myristica fragrans , Lawsonia inermis , Pelargonium odoratissimum (L.), Hagenia abyssinica , Calotropis gigantean , orange fruit peel, Ananas comosus fruit, Cocos nucifera leaf, and Catharanthus roseus leaf, have been reported to synthesize ZnO NPs. However, until now, all of the green synthesis processes of ZnO NPs have not been optimized properly, which reduces their effectiveness.…”

Synthesis and characterization of zinc oxide nanoparticles using peppermint tea (Mentha piperita) dregs extract and their photocatalytic performance

“…Well crystalline nature of ZnO NPs was indicated by the sharp diffraction peaks. The sharp diffraction peak (101) indicated the anisotropic development, implying on a preferred orientation of the crystallites 20 . However, there were some unrelated peaks (such as 28.62°, 32.64°, 42.71°, and 50.72°) which might be due to the impurities from the remaining of phytochemicals in the peppermint tea dregs extract.…”
