Abstract

Plant latex is a natural product produced by a number of plant species which are used by different tribal communities in India as a folk medicinal treatment on natural wounds or cuts. Plant latex has a huge demand as herbal products in an aspect of clinical, therapeutical and also in agricultural sectors. Natural latex is composed of different important biomolecules like, tannins, flavonoids, glycosides, sterols, saponins etc. These different active chemical constituents have versatile medicinal activities against different pathogens such as bacteria, fungi, viruses and protozoans etc. Therefore, development of novel biological techniques is significant for the biosynthesis of ZnO nanoparticles using the latex of Carica papaya L. This study reports on the biosynthesis of ZnO nanoparticles (Zn NPs) using latex of C. papaya as an effective reducing agent. Green synthesis of nanoparticles has advantageous over conventional methods because it does not require the use of toxic chemicals and therefore environmentally sustainable. Zinc oxide nanoparticles have gained potential recognition because of their distinctive characteristics and wide utilizatrion in various fields. Properties of synthesized ZnO NPs were characterized using various methods such as ultra violet visible spectrophotometer (UV-Vis), Scanning Electron Microscopy (SEM) and Fourier Transform İnfrared Spectroscopy (FT-IR). The elemental composition of C. Papaya latex was also analysed using X-ray Fluorescence (XRF) technique. Green synthesized ZnO nanoparticles also assessed for its antimicrobial activity against selected bacterial species.
