Abstract: New methods are needed to create integrated circuits which are able to overcome the inherent problems in the miniaturization process. These problems are mainly technological and economical; photolithography is limited and the expensive building respectively. This paper proposes the basis for a new manufacturing process of nanotechnological circuits based on semiconducting carbon nanotubes that work as FET (Field Effect Transistor) and metallic carbon nanotubes that work as nanowires. This process is based on the assembly of DNA tiles and lattices that guide the placement of carbon nanotubes to build electronic circuits. The process takes place in a microfluidic device within its chambers. Building blocks are created based on NAND logic gates. These building blocks are enabled to assemble AND, OR and NOT logic gates. The process of assembling a XOR logic gate is explained, demonstrating how to apply the process in a concrete case.
