Modern automobiles are faster, lighter, more comfortable, and increasingly efficient due to advancements in technology.

FREMONT, CA: Nanotechnology is a term that refers to scientific, technical, and technological applications that occur on a nanoscale. The nanoscale is concerned with materials with a diameter of one to one hundred nanometers, so small that they are undetectable to the naked eye.

Engineers and scientists control the very atoms that make up other materials when they deal with nanotechnology. They modify matter's physical and chemical properties. This level of accuracy permits excellent advancements, and changes in the way materials, parts, and gadgets interact with the surrounding environment.

While this topic has applications in a variety of industries, automakers have taken an interest in it. It is not an exaggeration to assert that nanotechnology has transformed the sector. This is how.

Reduced weights: Weight reduction is one of the most common applications of nanotechnology in the automotive sector. Lighter cars accelerate more quickly and consume less fuel, as they require less energy to move. Nanotechnology has the potential to develop innovative materials that give the strength that automobiles need without adding weight.

While steel and aluminum are relatively light in comparison to other metals, they are nevertheless somewhat heavy. Engineers can create polymers and carbon-based materials that are significantly lighter than these metals using nanotechnology. Components composed of some nanoengineered polymers can be up to 40% lighter than conventional steel components.

Along with developing new materials, nanotechnology can enhance current ones. Engineers can utilize nanotechnology to adjust the physical qualities of steel or aluminum, increasing their relative strength and allowing for comparable outcomes with less material.

More secure interiors: The inside of a vehicle is another significant application of nanotechnology in the automotive sector. Vehicle interiors are lined with plush materials such as felt and leather to enhance seat comfort. While these porous surfaces are pretty comfortable, they can trap bacteria and other microorganisms that could represent a health concern to passengers.

Metallic nanoparticles such as silver and titanium oxide have exceptional antibacterial characteristics that may address this issue. Numerous these nanoparticles degrade the cell membranes of pathogenic microorganisms while causing minor damage to humans. Hospitals have begun to rely heavily on them to sterilize equipment and make pharmaceuticals, and the automotive sector has followed suit.

Automobile makers can coat the inside of their vehicles with these metallic nanoparticles, thereby preventing disease spread. Similar coatings on the air filter of a car can also help eradicate hazardous bacteria from the air.
