The fundamentals of nanotechnology lie in the fact that the properties of materials drastically change when their dimensions are reduced to nano scale. The green synthesis of nanoparticles with the help of this plant extract was done for the first time. The leaves of the plant Nivdi was used for extraction of nano-ZnO, nano-Ag + and characterization of the nanoparticles was done through UV absorption and it shows absorption between 400 and 450 nm. The IR spectra denotes the presence of the following groups, i.e., C=C stretch, OH stretch, chelated H bond and NH stretching.

As we know that nanoparticles have a high surface to volume ratio because of its durability in function provided by this technology. Thus, the coating of the nanoparticle on the fabric does not changes the appearance or the feel of the fabric [1]. The nanoparticles have their essential parameters as: shape, size, surface characteristics and inner structure, which are important for their functions. Nanoparticles can be solids or liquids in air, suspension, i.e., solids in liquids or as emulsions. The interactions between the particles is due to weak Van der Waals forces, stronger polar and electrostatic interactions or covalent interactions [1, 2]. The interparticle interaction is mainly due to particle aggregation determined by viscosity and polarizability of fluids. MATERIALS AND METHODS Materials • Plant extract: Nivdi plant extract (Figure 1) • Chemicals used: a. Zinc acetate b. Silver nitrate Fig. 1: Plant leaf Nivdi. METHODOLOGY Green Synthesis of Nano-ZnO and Nano-Ag Extraction The extraction of the phyto-constituents of the plant is done from the plant leaf of Nivdi. It is an ancient plant which was typically used for wound healing for many decades. Firstly the plant leaves are washed with distilled water and sun dried [3]. As shown in Figure 2 leaves are further grinded to form into powder form. To this leaf extract distilled water is added and is heated at 40 degree for 1 hour (Figure 2b). The solution prepared is used further for green synthesis [4].
