What is Nanotechnology?
Nanotechnology is the science, engineering, and application of materials and devices with structures on the nanoscale, typically less than 100 nanometers. At this scale, materials exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts. This field encompasses a wide range of scientific disciplines, including physics, chemistry, biology, and materials science.
How has Nanotechnology Evolved?
The evolution of nanotechnology began with the visionary lecture by physicist Richard Feynman in 1959, titled "There's Plenty of Room at the Bottom." However, significant progress was made in the 1980s with the invention of the
Scanning Tunneling Microscope (STM) and the
Atomic Force Microscope (AFM), which allowed scientists to manipulate and visualize atoms and molecules. Since then, the field has rapidly advanced, leading to breakthroughs in various applications such as medicine, electronics, and materials science.
