This novel University of Chicago patent offers a commercial "free space method" based on field gradients in order to weave macromolecular films.
Claim 1 reads:
1. A method of constructing macroscopic films with tailored assemblies of molecules, comprising:
providing starting molecules; and
applying a force selected from the group of a gravitational force, a centrifugal force, a magnetic field force, and an electric field force to the starting molecules causing them to move in space and then chemically react to form tailored assemblies of molecules in a particular pattern in a nanoscale size macroscopic film for removal and subsequent use.
