DNA is the most important molecule for forming the basis of life.Whether and how DNA conducts electricity is highly related to the understanding and revelation of the transmission of life signals and life phenomena,as well as the development of programmable DNA molecular electronics.Thus,this topic has attracted tremendous attention worldwidely.However,DNA is a complex system that its conductivity property is still unclear and controversial.In this review,we briefly summarize the research history of DNA conductivity,analyze the main reasons for the controversy on DNA conductivity.The main problems existing in the study of DNA conductivity are mainly attributed to the diversity of measurement methods and the complexity of the DNA molecule.Finally,we propose the future development direction of DNA conductivity research.DNA conductivity has huge application potential in the fields of life signal transmission,biosensors,molecular electronics,etc.The research on DNA conductivity will also provide new ideas for the integration of biological science and electronics.
