MOSAIC is a single molecule analysis toolbox that automatically decodes multi-state nanopore data. By modeling the nanopore system with an equivalent circuit, MOSAIC leverages the transient response of a molecule entering the channel to quantify pore-molecule interactions. In contrast to existing techniques such as ionic current thresholding [PFR09][RKR10] or Viterbi decoding [Vit67], this technique allows the estimation of short-lived transient events that are otherwise not analyzed.
Nanometer-scale pores have demonstrated potential use in biotechnology applications, including DNA sequencing [KBBD96], single-molecule force spectroscopy [VDKD+09], and single-molecule mass spectrometry [RRS+07]. The data modeling and analysis methods implemented in MOSAIC allow for considerable improvements in the quantification of molecular interactions with the channel in each of these applications.
