Nanotechnology devoted to designing, producing, and using structures, devices, and systems by manipulating atoms and molecules at nanoscale. Nanotechnology is helping to considerably improve, even revolutionize, many technology and industry sectors: information technology, homeland security, medicine, transportation, energy, food safety, and environmental science, among many others. Nanotechnology, such as nanoscale biosensors and nanoparticles, to get an inside look at and manipulate processes like the spread of pathogens. Innovations in nanotechnology can help safeguard food security and protect the public from pathogens in food, water and the environment. Nanotechnology can help increase agricultural productivity, boost pest-resistance and improve food quality. It helps to enhance the productivity and consecutively the production of food. It can assist in providing opportunities for income generation. And, it generally provides improvement of nutritional advice through home economics programmes and enhances the quality of rural life by way of community development.

Nanotechnology can help increase agricultural productivity, boost pest-resistance and improve food quality. It helps to enhance the productivity and consecutively the production of food. It can assist in providing opportunities for income generation. Application of Nanotechnology to environmental issues for generating less pollution during the manufacture of materials and production of solar cells to generate electricity at a competitive cost to increase electricity generated by windmills for cleaning organic chemicals that pollute the groundwater. From saving raw materials, energy and water, to decreasing greenhouse gases and dangerous waste, nanotechnology's unique attributes can be utilized in various products, procedures and applications that could undoubtedly support environmental and climate protection. Nanotechnology, as nanoscale biosensors and nanoparticles, to get an inside look at and manipulate processes like the spread of pathogens. Innovations in nanotechnology can help safeguard food security and protect the public from pathogens in food, water and the environment. Therefore, by detecting pollutants by specific sensors, we can help protect the sustainability of human health and the environment. Thus, nanotechnology provides us with a new approach to cut down the waste production, reduce the emission of greenhouse gases and discharge of hazardous chemicals in water bodies. Nanotechnology offers many new strategies to reduce pollution in various processes, including improving production processes, reducing hazardous chemicals, reducing greenhouse gas emissions, and reducing the use of plastics and replacing plastics with biodegradable materials. Nanomaterials reaching in the land have the potential to contaminate soil, and migrate into surface and ground waters. Particles in solid wastes, waste water effluents, direct discharges, or accidental spillages can be transported to aquatic systems by wind or rainwater runoff.
