Description

Technical Field

[0001] The present invention relates to the field of nanotechnology, and particularly to an apparatus for manufacturing a nanocomposite composed of graphene oxide and silver nanoparticles (GO-Ag).

Background Art

[0002] Nanotechnology is the science of dealing with and utilizing materials and structures at the nanoscale, generally including dimensions smaller than 100 nanometers. In this field, materials and devices with excellent properties and capabilities due to their extremely small size can be manufactured and managed.

[0003] Nanotechnology is widely used in various fields such as electronics, medicine, materials science, and energy. Nanotechnology promotes significant progress and epoch-making technological innovations in these fields and is expected to have antibacterial effects against bacteria present in food.

[0004] Plant-mediated nanoparticle synthesis is a green chemistry that combines nanotechnology and plants. Plant-mediated synthesis, which mixes plants and nanotechnology, is an environmentally friendly method for manufacturing nanoparticles. New methods for manufacturing nanoparticles at room temperature, neutral pH, low cost, and in an environmentally friendly way are being studied. Nanomaterials have been made in many ways while keeping these goals in mind. Plants and plant extracts seem to be the most promising biological responses. Plants are nature's "chemical factories". They are low-cost and require almost no maintenance.

[0005] The development of efficient green chemistry techniques for making metal nanoparticles has become a major concern. Various methods for making well-characterized and ecologically beneficial nanoparticles are being studied. One of the most commonly mentioned methods is to utilize organisms to make metal nanoparticles. Plants make more stable nanoparticles than bacteria and do so more quickly. Furthermore, the size and shape of the nanoparticles are more diverse than those produced by other organisms.

[0006] H. tetrasperma is an antidiabetic plant commonly found in hilly areas up to an altitude of 2000 meters in Pakistan and open riverbanks. Most of the leaves grow in clusters at the tips of the branches of shrubs that are 1-2 m tall. The leaves are elliptical in shape as a whole, from acute angle to sub-acute angle, ovate-elliptical. The flowers are white and the fruits are spherical and purple.

[0007] Therefore, it is the demand of the times to utilize the advantages of nanocomposites with antibacterial activity derived from plants. These can help prevent and control the growth of harmful bacteria without using antibiotics through the creation of new antibacterial materials. In the research by the inventors, silver (Ag) nanoparticles, graphene oxide (GO), and graphene oxide nanocomposites with silver nanoparticles attached were synthesized using a green synthesis strategy, and their antibacterial and antioxidant properties were investigated.
