Examples of Nanofabrication
Nanofabrication is the design and manufacture of devices or materials at the nanometer scale (i.e., one-billionth of a meter) or involving structures smaller than about 100 nanometers. Here are three real-world examples of nanofabrication:
Nanoscale transistors: The ongoing miniaturization of electronic components has enabled the production of nanoscale transistors within microprocessors. Smaller transistors result in higher processing speeds and lower power consumption. Intel’s 10-nanometer technology, for instance, is used in the fabrication of its chips, which power various electronic devices such as computers and smartphones.
Nanosensors: Nanofabrication techniques have enabled the production of nanosensors, which are sensors with nanoscale elements. These sensors have a wide range of applications, including environmental monitoring, medical diagnostics, and industrial process control. For example, researchers have developed nanoscale gas sensors capable of detecting pollutants and chemicals at much lower concentrations than traditional sensors.
Drug delivery systems: Nanofabrication has led to advances in drug delivery technology, such as the development of nanoparticles that can deliver medication directly to specific cells or tissues in the body. This targeted drug delivery can improve the effectiveness of treatments and reduce side effects. One example is the use of liposomes, which are nanoscale vesicles made from lipid bilayers, to encapsulate and deliver drugs to cancerous tumors.
