Single nucleotide detection is important for early detection of diseases and for DNA sequencing. Monolayer (ML) MoS2 nanopores have been used to identify and distinguish single nucleotides with good signal-to-noise ratio in the recent past. Here, we use a bilayer (BL) MoS2 nanopore (∼1.3 nm thick) to detect distinct single nucleotides with high spatial resolution and longer dwell time. In this study, the performance of similar sized (
