A Naturally Efficient Computing Technique using Molecular Logic Gates with a DNA-cleaving Deoxyribozyme
By Vishnu Shankar
Current computational devices and techniques are based on silicon microprocessors. Computer manufacturers have been increasing transistor density on computer chip microprocessors at a rate that approximates Moore’s Law, which states that the amount of gates on a single chip will double every two years. Unfortunately, the application of Moore’s Law has been predicted to reach an end because of the physical speed and miniaturization limits of silicon microprocessors. The advantages of DNA Computing include large storage capacity and an ample a supply of DNA, making it a cheap natural resource unlike the cost of fabrication of Si-based computers. Even though empirically it has been shown that DNA computation has slower cycle than a silicon system, the parallel processing capabilities of a DNA system is significant in solving NP-hard problems. Further motivations for studying DNA Computing or the construction of molecular scale computing devices include its scale. Biological systems through superior control have been shown to solve many complex problems while avoiding the inefficiency of current von Neumann architecture ….
