Bio-synthesized Nano-formulation of Zinc Oxide – Aloe Vera and to Study Their Characterization and Antibacterial Activities against Multiple Pathogens

Nano-sized ZnO particles of specific morphology were synthesized using the plant leaf extracts of Aloe vera. In modern science Nanotechnology is an ablaze field for the researchers. Nanoparticles having a size of 1-100 nm in one dimension are used significantly concerning medical chemistry, atomic physics and all other known fields. Nanoparticles are used immensely due to its small size, orientation, physical properties, which are reportedly shown to change the performance of any other material which is in contact with these tiny particles. The biological approach is the most emerging approach of preparation, because, this method is easier than the other methods, eco-friendly and less time consuming. The semiconductor ZnO has gained substantial interest in the research community in part because of its large exciton binding energy 60 meV which could lead to lasing action based on exciton recombination even above room temperature. The Green synthesis was done by using the methanol of Aloe vera extract and zinc oxide. A fixed ratio of plant extract to metal ion was prepared and the color change was observed which proved the formation of nanoparticles. The nanoparticles were characterized by UVvis Spectrophotometer, FTIR Analysis, XRD, and SEM. INTRODUCTION: Nano materials have attracted tremendous interest due to their noticeable performance in electronics, optics, and photonics. Nano materials are typically classified into three groups: 0dimensional, 1-dimensional and 2dimensional. 0dimensional nanostructures, referred to as quantum dots or nanoparticles with an aspect ratio near unity, have been extensively used in biological applications 10 . Nanotechnology emerges from the physical, chemical, biological and engineering sciences where new techniques are being developed to probe and maneuver single atoms and molecules for multiple applications in different field of scientific world.

The science and engineering technology of nanosystems is one of the most exigent and fastest growing sectors of nanotechnology 12 . Zinc oxide (ZnO) is a class of inorganic metal oxides available and exhibits a wide range of nanostructures. Photocatalytic and photo oxidizing ability against chemical and biological species are used to characterize these metal oxides 21 . U.S. Food and Drug Administration have recognized ZnO as safe 11 . Lower cost, UV blocking properties, high catalytic activity, large surface area, white appearance and their remarkable applications in the field of medicine and agriculture are the advantages of ZnO particles 7 . Recently, ZnO have been used extensively in environmental remediation and antibacterial activity 14 .
