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.

Electrochemical guided mode resonance biosensor for simultaneous refractive index and electrochemical measurements

The paper introduces an electrochemical guided mode resonance biosensor that simultaneously measures refractive index and electrochemical properties.

Towards a bioelectronic computer: A theoretical study of a multi-layer biomolecular computing system that can process electronic inputs

This paper presents a theoretical study of a multi-layer biomolecular computing system that converts electrical inputs into biomolecular signals and performs logical operations.
