Nanotechnology, derived from the Greek word “nanos” meaning dwarf, refers to the science, engineering, and application of materials and devices at the nanoscale level. At this scale, materials exhibit unique properties and behaviors that differ from their macroscopic counterparts. By manipulating matter at such a tiny scale, scientists and engineers can create materials and devices with enhanced properties and functionalities.
2. What is Nanotechnology?
Nanotechnology involves the understanding, control, and manipulation of matter at the nanoscale, which typically ranges from 1 to 100 nanometers (nm). To put this into perspective, a nanometer is one billionth of a meter, about 100,000 times smaller than the diameter of a human hair. At this scale, the laws of classical physics give way to the principles of quantum mechanics, opening up new possibilities for exploration and innovation.
3. The Science Behind Nanotechnology
At the heart of nanotechnology lies the ability to engineer and manipulate materials at the atomic and molecular level. Scientists use various techniques, such as nanofabrication and self-assembly, to create nanoscale structures with specific properties. These structures can be tailored to exhibit desired characteristics, such as enhanced strength, conductivity, or reactivity.
