Molecular motor

In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work; for example, many protein-based molecular motors harness the chemical free energy released by the hydrolysis of ATP in order to perform mechanical work.

Some examples of biologically important molecular motors:[2] A recent study has also shown that certain enzymes, such as Hexokinase and Glucose Oxidase, are aggregating or fragmenting during catalysis.

Recently, chemists and those involved in nanotechnology have begun to explore the possibility of creating molecular motors de novo.

This has been demonstrated by using dye molecules that move directionally in gradients of polymer solution through favorable hydrophobic interactions.

[19] Another recent study has shown that dye molecules, hard and soft colloidal particles are able to move through gradient of polymer solution through excluded volume effects.
