An even better description of silver diffusion transfer by Drexler

Drexler's patent, though much later than Land's has a good description of the preparation of a receptor layer.

This and the Land patent contain subject matter that would later be important to late 20th century nanotechnology - particularly the  concepts surrounding distributions of electrically conducting nanoparticles in various substrates - something that I did extensive work in that can be seen at http://www.ambitcorp.com.


But you really should look at this Drexler patent instead.

Here is a link to that pdf

And here yet is another, much later patent on DTR on google patents here.
