Recently, the Center for Precision Medicine Single Molecule Diagnostic Technology Research of Chongqing Institute of Green Intelligence Technology of the Chinese Academy of Sciences, in collaboration with Tian Jian team of Nan kai University, made progress in the research on electrocution preparation solid-state nanopore technology and its 3D morphological manipulation, the results of which were published in the journal Applied Physics Letters under the title 3D nanopore shape control by current-stimulus dielectric. the
research team proposed a simple and effective electro-knock-through preparation solid nanopore technology to prepare conical 3D nanochannels on a 20nm silicon nitride film, gradually changing the current pulse waveform through the system, realizing the control of the nanochannel cone angle and nanochannel size, and preparing subnomethic channels that can be applied to bioreascement or precise DNA sequencing.
results show that the solid nanopores produced can be clearly divided into three dna ionosmers (poly(dA) 20, poly (dC) 20 and poly (dT)20).
the study was supported by the National Special Project for International Science and Technology Cooperation (2013DFA51430), the National Special Project for the Development of Major Instruments and Equipment (2013YQ030595), the National Natural Science Foundation of China (31527801,61471336) and the Western Joint Scholars Program of the Chinese Academy of Sciences (Wang Deqiang).
