[7] The associated research and applications are equally diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly,[8] from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. . Taking IoT to a whole new level is integrating Bio Nano technology. Nanotechnology radio receivers already exist. [1][2] A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defined nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). In general it is very difficult to assemble devices on the atomic scale, as one has to position atoms on other atoms of comparable size and stickiness. Nanobots are the real concern about wiping out humanity because they can be weapons of mass destruction, said Louis Del Monte, a Minnesota-based physicist and futurist. The main reason is the cytotoxicity and safety profile of NPs and their unknown impact on stem cell differentiation [73, 118]. Nanotechnology is the supramolecular technology, which means, it is the engineering of functional systems at the molecular or supramolecular scale. This roughly translates to the the molecular and atomic levels in some cases. The tip of a scanning probe can also be used to manipulate nanostructures (a process called positional assembly). For instance, opaque substances can become transparent (copper); stable materials can turn combustible (aluminium); insoluble materials may become soluble (gold). Current volume Number 18, 30 April 2023. Researchers currently study living cells using a technique called Raman spectroscopy. According to Del Monte, nanoweapons are much smaller than a strand of human hair and the insect-like nanobots could be programmed to perform various tasks, including injecting toxins into people or contaminating the water supply of a major city. Technically speaking, nanotechnology is any technological endeavor that deals with anything with a dimension of fewer than 100 nanometers.
