Zusammenfassung:Green synthesis of nanoparticles has many advantages over conventional physico-chemical methods and has extensive applications in the field of medicine and biology. In this study, zinc oxide (ZnO-NP) nanoparticles were synthesized from aloe vera leaf extract. 0.25M zinc sulfate was used as the zinc precursor. The presence of white precipitation from the reaction indicated the formation of ZnO-NP. The characterizations of ZnO-NP were determined using a variety of analytical methods such as X-ray diffraction (XRD), field-discharge scanning electron microscope (FESEM), ultraviolet-visible spectrophotometer (UV-Vis) and transmission electron microscope (TEM). The UV peak was formed at 380 nm while the XRD diffractogram corresponded to the JCPDS card for crystalline ZnO, confirming the presence of pure ZnO-NP. FESEM analysis revealed agglomerated ZnO-NP in irregular shapes whereas TEM showed nanoparticles with sizes ranging from 20 to 90 nm. The results of this study indicated that plant-based ZnO-NP synthesis is feasible and can be an excellent strategy for developing versatile and environmentally friendly products.
