Nanotechnology is an area of technology and design that involves influencing subject on a nanoscale, wherever sizes are typically significantly less than 100 nanometers (a nanometer is one-billionth of a meter). As of this scale, products show unique bodily, compound, and scientific properties that may be harnessed for progressive applications across numerous industries. This information considers the fundamentals of nanotechnology , its applications, advantages, challenges, and future prospects.
What is Nanotechnology ?
Nanotechnology may be the technology of design and using products at the nanoscale.
