Development of Nanomaterials Based Sensor for Agriculture Pest Management

Abstract

Nanotechnology is the fastest growing science, with numerous applications in newlineagriculture, plant science, environmental engineering, pharmacy, photon energy, newlinemedical science, fisheries, and the marine industries. Above all other industries, newlineagriculture plays a crucial role in the entire life and economy. Due to the newlineoverloading global population, the present food production rate is not sufficient to newlinebalance the food scarcity. The food production rate was often limited by many newlineenvironmental factors including soil contamination, water pollution, water scarcity, newlinemicrobial infections, weeds, pests, salinity, drought, heavy metals stress, and limited newlineavailability of land. Out of these factors, plant pest causes a significant crop loss newlineannually and become a global threat to agriculture. In the present condition, it is an newlineurgent need to concentrate on food security and plant pest management system. Many newlinerecent studies are proved that nanotechnology is a potential alternative to newlineconventional farming and it helps to improve crop yielding and disease resistance. In newlineaddition, various nanoparticle-based formulations such as fungicides, fertilizers, newlineherbicides, and pesticides have already been experimented in many plant systems for newlineplant growth and development. Apart from this, nanomaterials-based sensors are the newlinetopic today and the main goal is to promote all scientific sectors including agriculture newlinethrough sustainable approach. There are several methods were employed in newlinenanoparticles synthesis worldwide. In this study, I used chemical and green synthesis newlineof zincoxide nanoparticles. One of the components necessary for life and a cofactor newlinefor many biological enzymes, ZnO nanoparticles (NPs) have garnered observation newlinedue to their availability in the cell (biocompatibility). Additionally, it possesses the newlineproperty of a large area-to-volume ratio that helps to provide conductivity, stability, newlinecatalytic, and various anti-microbial, anti-cancer, and electrochemical sensing newlineproperties. The goal of the present study is to synthesize ZnO NPs using Ocimum newlinesanctum extracts, development of ZnO nanowires (ZnO NWs), and synthesize newlinepolymer-based nanomaterial (Chitosan-Sodium Alginate), and development of a newlinesensor for agriculture pest management. In this study, the following objectives are newlinefocused on, (i) synthesis, characterization of ZnO NPs using green and chemical newlinemethods, (ii) synthesis, characterization of ZnO NWs, (iii) synthesis, characterization, newlineand assessment the effect of alginate (AG) and chitosan (CS) polymer-based newlinenanomaterial (AG/CS NPs) on the life cycle of green lacewing, and (iv) development newline newlineof RGO-ZnO nanocomposite electrochemical sensor for detecting the agrochemicals newline(Carbofuran and Methyl viologen). The outcome of this study allows us to develop newlinethe agriculture sector using nanoscience and technology. newline
