This is what a lab on a chip is https://en.wikipedia.org/wiki/Lab-on-a-chip
I ask if could be used as a nuclear fusion device , that could rise the number of nuclear fusion per atom, knowing that microchannels can mix better substances?
Microchannels could be made by engineering means, like photolithography , already are made microchannels at the size of few micrometers
Microchannels could be working either by light either by small electromagnets
I think that could work because the nanochannels or microchannels could be used one time, as pellets are used in the laser driven nuclear fusion.
Could be used, burnt , and replaced with another pellet like usual pellets are used in the laser driven nuclear fusion.
It's just needed that a continous flow of pellets like this to be used
Notice that i spoke about a microchannel that works either by light either by small electromagnets.
The substances , or in this case of fusion, the ions could be moved by a magnetic field
As far as i know ions could be moved no matter how small a channel could be , by a magnetic field
Laminar flow would not be a problem since the number of molecules involved in fusion would be small
