Some proponents of nano-robotics, in reaction to the grey goo scenarios that they earlier helped to propagate, hold the view that nano-robots able to replicate outside of a restricted factory environment do not form a necessary part of a purported productive nanotechnology, and that the process of self-replication, were it ever to be developed ...
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter. This definition of nanotechnology includes all types of research and technologies that deal ...
Nanomanufacturing refers to manufacturing processes of objects or material with dimensions between one and one hundred nanometers. [15] These processes results in nanotechnology, extremely small devices, structures, features, and systems that have applications in organic chemistry, molecular biology, aerospace engineering, physics, and beyond.

Nanotechnology is an active research area that encompasses a number of disciplines such as electronics, bio-mechanics and coatings. These disciplines assist in the areas of civil engineering and construction materials. [22] If nanotechnology is implemented in the construction of homes and infrastructure, such structures will be stronger.
In semiconductor manufacturing, the 2 nm process is the next MOSFET (metal–oxide–semiconductor field-effect transistor) die shrink after the 3 nm process node.. The term "2 nanometer", or alternatively "20 angstrom" (a term used by Intel), has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors.
To build meaningful "machines" at the nanoscale, the relevant forces need to be considered. We are faced with the development and design of intrinsically pertinent machines rather than the simple reproductions of macroscopic ones. All scaling issues therefore need to be assessed thoroughly when evaluating nanotechnology for practical applications.
Nanocomputers might be built in several ways, using mechanical, electronic, biochemical, or quantum nanotechnology. There used to be consensus among hardware developers that it is unlikely that nanocomputers will be made of semiconductor transistors , as they seem to perform significantly less well when shrunk to sizes under 100 nanometers.

In 2003, a research team at NEC fabricated the first MOSFETs with a channel length of 3 nm, using the PMOS and NMOS processes. [20] [21] In 2006, a team from the Korea Advanced Institute of Science and Technology (KAIST) and the National Nano Fab Center, developed a 3 nm width multi-gate MOSFET, the world's smallest nanoelectronic device, based on gate-all-around technology.
