To create, characterize, fabricate, and utilize materials, structures, devices, and systems, nanotechnology refers to the study and application of phenomena that occur on the nanoscale scale. Despite the fact that nanoscale structures have been employed in numerous technologies for quite some time and that there are many examples of nanometer-sized systems in nature, such as molecules in the human body system and dietary ingredients. Controlling matter at the nanoscale scale is what sets nanotechnology apart from other technologies.
There is no doubt that various forms of nanotechnology could have far-reaching impacts on human culture. Everybody and everything stands to gain from the widespread use of nanotechnology. Most of these uses include novel materials with drastically different properties because they operate on the nanoscale. Very thin films are used in catalysis and electronics, while two-dimensional nanotubes and nanowires are put to use in optical and magnetic systems, and nanoparticles are incorporated into a wide variety of products, including cosmetics, medications, and coatings. Industries that have been quick to adopt nanotechnology include the information and communications sector, the food technology sector, the energy technology sector, and the medical products field. It’s possible that nanotechnology products will introduce novel difficulties in the fight against pollution.
What Is Nanotechnology?
The term “nanotechnology” refers to the branch of science and engineering that is focused on the design, production, and use of structures, devices, and systems that are created by manipulating atoms and molecules at the nanoscale. This means that the dimensions of these structures, devices, and systems must have one or more dimensions that are on the order of 100 nanometers (100 millionth of a millimeter) or less.
The father of nanotechnology is physicist Richard Feynman. The subjects of chemistry, biology, physics, materials science, and engineering can all benefit from the exploration and use of nanoscience and nanotechnology, the study and application of extremely small things.
Applications Of Nanotechnology
Food Industry
Nanoparticles, such as Silver, are mixed with polymers to improve the quality of food packaging materials, which makes the food last longer. Nanotechnology is also important because it can be used to make “smart packaging” that can tell when biological changes are happening in food. In agriculture and agribusiness, nanotechnology is used in different ways to make sure that food is safe. Nanotechnology is important in food processing because it helps improve the texture, appearance, taste, nutritional value, and shelf life of food.
Automotive Technology
During the course of the last ten years, the automotive sector saw a massive change. Innovative types of four-wheelers and two-wheelers that are powered by cutting-edge technology are introduced periodically. This is another sector of the economy where the uses of nanotechnology are beginning to become apparent. To increase the tires’ resistance to abrasion, numerous polymer nanocomposites, such as natural rubber-organoclay, have been used in their construction. In addition, the mechanical properties of automobile fluids have been improved as a result of the addition of nanoparticles, such as tungsten nanospheres.
Chemical Catalyst
Catalysts made of nanoparticles are used to speed up chemical reactions. This aids in lowering the number of resources required to produce the desired outcome. By doing so, you can save money and lessen the production of pollutants. The two main uses are in vehicle catalytic converters and petroleum refining.
Enhancing Water Quality
One of the best uses of nanotechnology is to enhance water quality by eliminating chemical and industrial pollutants like TCE from rivers and groundwater using special nanoparticles on filter membranes. Water treatment with nanotechnology is very effective and relatively less expensive.
Composite Materials
Nanoscale additives in polymer composite materials are utilized to reduce the weight of automobiles, airplanes, and aircraft. Carbon nanotube sheets are being employed in next-generation aircraft to improve fuel efficiency.
Electronics
A wide range of goods, including wearables, medical devices, and aerospace applications, are using bendable and stretchable electronics. In “tattoo” sensors, sewable photovoltaics, and rollable electronic paper, nanomaterials including graphene and cellulosic materials are being employed.
Medicine
Patients experience significant side effects from a variety of therapies and medications for chronic disorders like cancer, brain tumors, etc. Nanoparticles are being used in this situation so that the medicine can be directed to the affected cells rather than the entire body. In addition, a wide variety of nanomaterials are being applied to improve the effectiveness of imaging technology. In addition to the aforementioned fields, gene therapy, wound care, etc. are more examples of how nanotechnology is used in medicine.
Solar Cells
Solar panels can more effectively generate power by using nanotechnology. Manufacturers are able to print flexible, rollable panels. Thin-film solar electric panels are being developed by researchers to be mounted on computer boxes and utilized as a portable power source.
Textiles And Fabrics
Specialized fabrics containing nano-sized Titanium and Silver particles are being used to create clothing that is wrinkle-free, odor-free, and wearable throughout the seasons. As a result, breathable, lightweight textiles have been created. Nanotechnology is also used in this sector to improve durability and stain resistance in textiles.
Chemical Detection
Chemical or biological agents in the air and soil can be found and identified using nanotechnology sensors. To identify compounds in the air, researchers are examining various particles. Researchers are figuring out how to use each one’s distinct chemical and physical features for the rehabilitation of toxic sites.
Improving Air Quality
Air quality is getting worse all over the world, and nanomaterials are being used a lot to fix this problem. On the one hand, nanomaterials such as Graphene Oxide are utilized to coat membranes that are used to differentiate pollutants from the air. On the other hand, studies are being carried out to enhance the performance of catalysts, which can significantly lower the effects of air pollution from factories, cars, air conditioners, and other sources. Nanoparticles make up these catalysts, which give the chemicals a lot of space to react.
Conclusion
Over the last few decades, nanotechnology has grown in popularity as an appealing technology that has altered many industries. It is a nanometer-scale technology that works with atoms, molecules, or macromolecules with sizes ranging from 1-100 nm to make and use materials with unique features. As a result, Nanotechnology has applications in a wide range of sectors. Nanotechnology advancements have altered a variety of scientific and industrial fields, including the food business.
