Identification of single nucleotides in MoS₂ nanopores. (a) Schematic of the DNA homopolymer translocation detection. The cis reservoir contains room temperature ionic liquids (BmimPF6) and the trans reservoir contains 2 M aqueous KCl solution. Two reservoirs are separated by a monolayer MoS₂ membrane with a nanopore. (b) Translocation signals for each DNA homopolymer in a 2.8 nm MoS₂ nanopore: poly A30 (green), poly C30 (red), poly T30 (blue), and poly G30 (orange). (c) Normalized histogram of current drops for each DNA homopolymer (reprinted with permission from [119], copyright 2015, Springer Nature).
