Q & A
What is nanotechnology?
-Nanotechnology is the science and engineering of manipulating matter at the atomic and molecular scale, typically between 1 and 100 nanometers. At this scale, materials exhibit unique properties that differ significantly from their larger-scale counterparts.
How small is a nanometer?
-A nanometer is one billionth of a meter, which is incredibly small. To give a sense of scale, it is approximately 100,000 times smaller than the diameter of a human hair.
What are the different types of nanotechnology?
-Nanotechnology can be categorized into several types, including: nanomaterials (engineered at the nanoscale such as nanoparticles, nanowires, and nanofibers), nanoelectronics (use of nanotechnology in electronic components), nanomedicine (application in healthcare for diagnostics, drug delivery, and disease treatment), and nanosensors (used in environmental monitoring, healthcare, and industrial applications).
How does nanotechnology benefit medicine?
-In medicine, nanotechnology enables targeted drug delivery, which allows drugs to be delivered directly to specific cells (such as cancer cells), minimizing damage to healthy cells. It also improves imaging techniques and helps develop new therapies.
What role does nanotechnology play in electronics?
