AbstractIn this work, the conductivity of DNA molecules under the effect of magnetic fields was studied by conductive atomic force microscopy (C-AFM). It is found that the self-assembly images of 7.5 ng/μL DNA aqueous solution on the bare mica and Au layer surfaces are quite different, and the DNA molecules are obviously stretched on the Au layer surface and single stretched DNA strands were obtained. In addition, the conductivity of single stretched DNA molecules in the horizontal stable magnetic field (SMF) and high frequency electromagnetic field (HFEF) were investigated in detail. The results showed that the conductivity of DNA was weakened by the effect of magnetic field.
