Single molecule nanopore sensing across a liquid-solid interface

This paper demonstrates single-molecule nanopore sensing using a solid polymer electrolyte instead of liquid electrolytes, enhancing sensitivity and enabling robust, portable sensing platforms.

Empirical Validation of Composite Fractional Noise Models in Nanopore Signals

This study empirically validates a composite fractional noise model for nanopore signals across diverse experimental conditions, showing it accurately captures noise structure and separates deterministic from stochastic components.

Visualizing and Quantifying microRNA Induced DNA Origami Separation at the Nanoscale

This paper presents a method using DNA origami disassembly driven by miRNA to detect small RNA, showing robust detection in RNAse-containing environments.

Electronic Actuation of Surface-Immobilized, pH-Responsive DNA Nanoswitches

This paper demonstrates pH-responsive DNA nanoswitches immobilized on surfaces, showing reversible and repeatable switching, and introduces electrically driven actuation for potential hybrid electronic-DNA technologies.
