Length‐Independent Charge Transport in Chimeric Molecular Wires

Abstract

Advanced molecular electronic components remain vital for the next generation of miniaturized integrated circuits. Thus,muchresearcheffort has been devoted to the discovery of lossless molecular wires,for whichthe charge transport rate or conductivity is not attenuated with length in the tunneling regime.H erein, we report the synthesis and electrochemical interrogation of DNA-like molecular wires.W edetermine that the rate of electron transfer through these constructs is independent of their length and propose aplausible mechanism to explain our findings.The reported approach holds relevance for the development of high-performance molecular electronic components and the fundamental study of charge transport phenomena in organic semiconductors.

DNA Generated Electric Current Biosensor

“…Molecular scale electronics have the potential to overcome the limitations of conventional silicon-based integrated circuits, enabling Moore’s law to be extended beyond the limits of conventional electronics . DNA has been utilized in molecular electronics to conduct charge − and for logic gating. , DNA is also used for label free detection. In addition, we hypothesize that DNA can be used as a biological electric current source using the chemical energy stored in its bonds or the electrical charge of the molecules on the DNA phosphate backbone.…”
