Steven Surgnier ELEC 7770 April 05, 2009 DNA nanostructures are opening up new research areas that require a wide breadth of knowledge, borrowing techniques from the fields of computer science, electrical engineering, biology, physics, and biochemistry. Since the self assembly of DNA strands occurs naturally at the molecular level, DNA nanostructures can be actualized autonomously. Thus, the physical limitations of top-down approach to photolithographic processes can be overcome. The field of DNA computing began with the success of Leonard Aldeman’s experiment in 1994. In the experiment he solved a seven node instance of the Hamiltonian Graph problem (similar to the travelling salesman problem) with the use of DNA. The first step towards a DNA computer was achieved with the MAYA-I at Columbia University. MAYA-I which stands for Molecular Array of YES and AND/NOT logic gates, is composed of 23 logic gates and can play specific games of tic-tac-toe. MAYA-II has more than 100 logic gates and can play all forms of
