The history of nanotechnology traces the development of the concepts and experimental work falling under the broad category of nanotechnology.Although nanotechnology is a relatively recent development in scientific research, the development of its central concepts happened over a longer period of time.
Nanomedicine is the medical application of nanotechnology. [1] Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology such as biological machines.
Nanotechnology is the science and engineering of functional systems at the molecular scale. In its original sense, nanotechnology refers to the projected ability to construct items from the bottom up making complete, high-performance products. One nanometer (nm) is one billionth, or 10 −9, of a meter.

When the blood vessels form so rapidly, large fenestrae result that are 100 to 600 nanometers in size, which allows enhanced nanoparticle entry. Further, the poor lymphatic drainage means that the large influx of nanoparticles are rarely leaving, thus, the tumor retains more nanoparticles for successful treatment to take place. [8]
However, as with nanotechnology and biotechnology, bionanotechnology does have many potential ethical issues associated with it. A ribosome is a biological machine . The most important objectives that are frequently found in nanobiology involve applying nanotools to relevant medical/biological problems and refining these applications.
] Scientists report an organ perfusion system that can restore, i.e. on the cellular level, multiple vital (pig) organs one hour after death (during which the body had warm ischaemia), [285] [286] after reporting a similar method/system for reviving (pig) brains hours after death in 2019.
Due to their nanoscale dimensions, electron transport in carbon nanotubes will take place through quantum effects and will only propagate along the axis of the tube. These electrical and structural properties best serve CNTs as far as biosensing is concerned because current changes in the CNTs can signify specific biological entities they are ...
