Nanotechnology involves the manipulation of matter at the atomic and molecular scale, typically within the range of 1 to 100 nanometers. It seeks to design, create, and utilize structures, devices, and systems by controlling shape and size at the nanometer scale. This technology has numerous applications across various fields, including
medicine,
electronics,
energy, and
materials science.
The implementation of nanotechnology involves several
techniques and
tools. One prominent method is
lithography, which is used to create patterns on a nanoscopic scale. Another important technique is
self-assembly, where molecules autonomously organize into structurally well-defined arrangements. Additionally, methods like
electron beam lithography and
scanning tunneling microscopy play a significant role in the precise manipulation and observation of nanostructures.
Nanotechnology has transformative potential across a wide array of sectors:
