What is difference between molecular electronics & Nano electronics ?

How molecular electronics is related with Nano electronics..?

'Nano' has grown to be associated with nanobots, nano probes, nanomotors... Electronic devices of microscopic size, individually.

Molecular is the scale of miniaturization which research and development seems to aim for as they make ever-smaller electronic circuits and cpu's. How small are the limits? Track widths become more narrow. Doping of silicon is done to a finer resolution.

How molecular electronics is related with Nano electronics..?

The difference is just a matter of scale.

One hydrogen atom is only 0.1 nm; one nanometer is 10^(-9) meter.

Proteins and other macromolecules are about 3-4nm; gold nanoparticles are about 10-50nm in diameter.

Nanoelectronics refers to scales in the broad range of 1-100nm. In the low range, it will overlap with many biological macromolecules.

When the particle size is around 10nm or less, it begins to show quantum effects (like quantum dots etc)

Much of our semiconductor technology is currently in the nano range.
