A nanomotor is a molecular or nanoscale device capable of converting energy into movement. It can typically generate forces on the order of pico-Newtons. The applications consists of directed drug delivery and novel treatments in nano-onchology. For instance, those nanomotors are categorized as below:
1- Molecular motor proteins found in living cells.
2- DNA nanomachines.
3- Chemically powered or UV triggered artificial nanomotors.
4- Catalytic nanowire motors, such as Pd-CNT nano tube and fuel-driven catalytic nanomotors.
5- Bubble-powered catalytic microtube microengines.
etc.
Your comments are appreciated !?
In your definition, the "nanomotor" concept seems to be an engineering description or extension of the concept of chemical reaction pathways proceeding either through equilibrium (thermodynamic) or kinetic processes. Implicit in this concept, as applied for drug delivery, is a way to drive the device containing the nanomotor to its desired destination. The energy absorbed by the nanodevice might also be used to power the "intelligence" of the driver as well. Intelligence might be defined as the design of the nanodevice in such a way as to take advantage of known bias the pathway, such as leaky blood vessels in young metastatic cells, or some diffusion-controlled process occurring through a cell wall, etc. Does this help?
Very Fantastic Idea
Fabricating prototypes of artificial nano-motors.
Creating nano-motors that could travel through the body to manage insulin for diabetics or pumping biochemicals and travel through fluids.treat tumor cells without hurting the good cells.
I recommend to see Vincenzo Balzani et al work in this area.
"Autonomous artificial nanomotor powered by sunlight"
Natural molecular motors, however, are extremely complex, and any attempt to construct systems of such a complexity, using the bottom-up molecular approach, would be challenging. What can be done, at present, is to construct simple prototypes of artificial molecular motors and machines ,con- sisting of a few components capable of moving in a controllable way, and to investigate the associated problems posed by inter- facing them with the macroscopic world particularly as far as energy supply is concerned.
Dear George and Behzad
The human body fabricates many nanomotors of different kinds.To my knowledge, those are vital in the cell performance indicating the nano-intelligence too.
