Brief Overview

Here is a brief overview of a few current applications of nanomaterials. They primarily represent evolutionary developments of existing technologies. 

Nanomaterial Uses
Nanocomposites 

Nanoparticles and nanotubes have an important role to play in composites. Carbon fibres and bundles of multi-walled CNT’s are used in polymers to enhance and control connectivity. 
Nanocoatings and Nanostructured Surfaces Coatings with thickness at nano or atomic scales are in active production. The self-cleaning window is one of the most recently developed products in this line.
Tougher and Harder Cutting Tools  Nanocrystalline materials are used to make cutting tools such as Tantalum Carbide and Tungsten Carbide. They are erosion resistant and last longer.
Nano lubricants  The inorganic materials of nanospheres are used as lubricants. They are more durable as compared to conventional solid lubricants. 

Food Industry

Nanoparticles like Silver mixed with polymers are being used to enhance the quality of food packaging material thereby increasing its shelf life. making it last longer and taste better. Furthermore, “smart packaging”, through which biological changes occurring in the food are detected is also one of the significant applications of Nanotechnology.  Keeping in mind the assurance of food safety, various applications of nanotechnology are involved in agriculture and agri-business. 

Electronics and Devices

With the advancement in technology, we have shifted from bulky Television sets and mobile phones to sleek TV sets and smartphones. Moreover, with the use of nanomaterials like Graphene, thin, lightweight, better quality TV screens which also consume less power have been invented!

Medicine 

Various treatments and medicines for chronic diseases like cancer, brain tumor, etc have severe side effects on the patients. For this, Nanoparticles are being utilised wherein, the drug will be targeted to the infected cells instead of the whole body. Apart from this, a wide range of nanomaterials is being used to enhance the efficiency of imaging devices. Medicinal applications of nanotechnology are not only restricted to the aforementioned areas but are also seen in gene therapy, wound treatment, etc. 

Textiles and Fabrics

To make a piece of cloth wearable, wrinkle and odor-free across seasons, specialized fabrics with nano-sized Silver and Titanium particles are being used. This has led to the production of lightweight, thin and breathable fabrics. The other applications of Nanotechnology in this industry include making fabrics stain-resistant and improving durability.

Automobiles 

The automobile industry has seen a paradigm shift in the past decade. Every now and then, new four- and two-wheeler models are launched which work on extra-edge technology. This is yet another industry where the applications of Nanotechnology are visible. Various polymer nanocomposites like Natural Rubber-Organoclay have been used in tyres to make them abrasion-resistant. Furthermore, adding nanoparticles like tungsten nanospheres to car fluids has enhanced their mechanical properties. 

Sporting Equipment and Goods

In today’s society, different types of co-curricular activities like sports have become a popular choice for building a career. And due to this, many revolutionary changes are being made, especially in Tennis and Golf. With the use of nanomaterials like Silica nanoparticles, nanoclays fullerenes, etc, high-end racquets, new tennis balls through which air releases at a slow pace, lightweight hockey sticks, and club shaft material with improved durability have been made. 

Enhancing Water Quality

This is one of the best applications of Nanotechnology where unique nanoparticles are used on filtration membranes to improve the quality of water by removing chemical and industrial waste such as TCE from the river and groundwater. Using Nanotechnology for purification of water is highly effective and comparatively cheaper. 

Space Science

Another domain where the applications of Nanotechnology is visible is Space Science and Research. Apart from making the outer structure of satellites durable and lightweight using materials like CNT, research is also being done on how to send spacecraft with lesser fuel.

Improving Air Quality 

Deteriorating air quality has become a global issue and for this, nanomaterials are being used extensively. On one hand, membranes coated with nanomaterials like Graphene Oxide are being used to separate pollutants from the air. While on the other, research is being conducted to improve the efficiency of catalysts which can help in minimizing the effect of air pollutants from industrial plants, cars, air conditioners, etc. Such catalysts, which are made up of nanoparticles provides a large surface area for the chemicals to react. 

Chemical Sensors

Using nanomaterials like Zinc Oxide nanowires, Carbon nanotubes as well as palladium nanoparticles, various sensors have been designed which can easily detect even the smallest amounts of hazardous chemicals. This has been made possible as the electrical properties of these materials enhance at the nano-level.

Benefits and Applications of Nanotechnology
