What is Nanotechnology?
Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale. It involves the design, production, and application of structures, devices, and systems by controlling shape and size at the nanometer scale (1 to 100 nanometers). This field encompasses a broad range of scientific disciplines including physics, chemistry, materials science, and engineering.
Why is Nanotechnology Important?
Nanotechnology has the potential to revolutionize various industries by providing new materials and methods for
medicine, electronics, energy production, and environmental protection. For example, in medicine,
nanoparticles can be used for targeted drug delivery, thereby reducing side effects and improving treatment efficiency. In electronics,
nanoscale transistors can lead to faster and more efficient devices.
