Nanotechnology
Nanotechnology is the engineering and manipulation of matter at the nanoscale, typically involving structures and devices between 1 and 100 nanometers in size. At this scale, materials exhibit different physical and chemical properties compared to their bulk counterparts due to increased surface area and quantum effects. This enables novel applications that would be impossible with conventional manufacturing approaches.
Applications and Fields
The field spans multiple industries including semiconductors, where nanoscale transistors form the basis of modern computing; materials science, where nanoparticles and nanocomposites create stronger or more functional materials; medicine, where nanoparticles can deliver drugs or enable diagnostics; and manufacturing, where precision at the nanoscale allows creation of advanced components. Semiconductor manufacturing represents one of the most mature applications, with modern processors featuring transistors measured in nanometers.
Development and Tools
Nanotechnology emerged in the late 20th century as advances in microscopy and fabrication tools made it possible to observe and manipulate matter at the atomic and molecular level. Key enabling technologies include scanning tunneling microscopes, atomic force microscopes, and various lithography techniques that allow precise patterning and assembly of nanoscale structures.
