Biology is Nanotechnology

Biological systems operate using nanotechnology. The cell (plant and/or animal) is inherently nano in scale hence nanotechnology has to merge with biology. In order for molecular engineering of nanomachines to be possible then we have to view nanotechnology as biology. Smaller than nano is pico and femto-technology which are far below atoms and other elements of nature that are visible to the naked eye. In cellular biology, ATP synthesis and DNA replication are essential tasks of life which are done by nanites or molecular machines. Molecular machines can be divided into two broad categories: artificial and biological. Artificial molecular machines are molecules that are artificially designed and synthesized while biological molecular machines are molecules that are found in nature and have evolved after abiogenesis on Earth. The most complex macromolecular machines are found within cells, often in the form of multi-protein complexes. Examples of biological molecular machines include motor proteins such as myosin (for muscle contraction), kinesin (moves cargo inside cells away from the nucleus), dynein (moves cargo inside cells towards the nucleus). Examples of artificial molecular machines include molecular sensors, molecular switch, molecular shuttle, molecular propeller.

Molecular machines will play an integral role in genetic engineering and as a result will impact medical laboratories. This is a new form of bioengineering which could lead to the creation of synthetic plants and animals.
