A Novel Reconfigurable Logic Unit Based on the DNA‐Templated Potassium‐Concentration‐Dependent Supramolecular Assembly. Issue 16 (31st January 2018) - Yang, Chunrong
Abstract: Plenty of molecular circuits with specific functions have been developed; however, logic units with reconfigurability, which could simplify the circuits and speed up the information process, are rarely reported. In this work, we designed a novel reconfigurable logic unit based on a DNA‐templated, potassium‐concentration‐dependent, supramolecular assembly, which could respond to the input stimuli of H + and K + . By inputting different concentrations of K +, the logic unit could implement three significant functions, including a half adder, a half subtractor, and a 2‐to‐4 decoder. Considering its reconfigurable ability and good performance, the novel prototypes developed here may serve as a promising proof of principle in molecular computers. Abstract : It′s logical captain ! A multifunctional logic unit based on a DNA‐templated potassium‐concentration‐dependent supramolecular assembly was constructed to implement three significant logic functions, including a half adder (HA ), a half subtractor (HS ) and a decoder (DC ).
