Electrical Resistance of Some Types of Homooligonucleotides
摘要
Abstract
We presented the results of a study of the electrical resistance of two types of short single-stranded DNA molecules consisting of only one type of nucleotides, dA or dC, using scanning tunneling microscopy and spectroscopy. It was found that the resistance of dC12 homooligonucleotides is slightly higher than that of dA12 homooligonucleotides.
