Patent ID: 8642354

Claim:
A method comprising: introducing a fluid including a first monomer into a first fluid distribution manifold of a fluid processing device; opening, by a controller, a closed surface tension control valve in fluid communication with both the first fluid distribution manifold and at least one respective reaction site, to form an open surface tension control valve, wherein opening the closed surface tension control valve allows flow of the fluid to contact the at least one respective reaction site, wherein the surface tension control valve is configured to be actuated by electromagnetic radiation directed at the surface tension control valve to change a contact angle of the fluid to a surface of the surface tension control valve, wherein the at least one closed surface tension control valve is disposed between the first manifold and the at least one respective reaction site, and wherein the open surface tension control valve is configured to allow the first monomer to move from the first manifold, through the open surface tension control valve, and into the at least one respective reaction site; and forming an extended structure by the first monomer attaching to a first structure in the at least one respective reaction site.
