Latent space mapping of interpretable structural coordinates from stochastic single-molecule signals
arXiv:2606.16950v1 Announce Type: cross Abstract: Nanopores are versatile single-molecular sensors, but their utility is fundamentally constrained by stochastic translocation dynamics warping any encoded information. We resolve it by shifting from time-domain analysis to a learned latent-space mapping via a contrastive encoder trained exclusively on simulated signals from a physics-informed model. This encoder maps solid-state nanopore signals of engineered DNA barcodes into an interpretable molecular coordinate system. The learned representation is responsive to structural barcode parameters
This development, published on arXiv, leverages recent advances in AI and 'physics-informed models' to overcome a fundamental limitation in nanopore sensing, indicating a maturing convergence of these fields.
The ability to accurately interpret stochastic single-molecule signals via AI could unlock significant advances in diagnostics, drug discovery, and materials science, impacting a range of high-value applications.
This shifts nanopore analysis from complex time-domain interpretation to a more robust and interpretable latent-space mapping, promising higher accuracy and broader utility for single-molecule sensing.
