Atom-Sized Gates Revolutionizing Technology

Scientists at The University of Osaka have mimicked nature's tiniest ion channels by creating subnanometer pores. These pores, formed in a silicon nitride membrane by an electrochemical reactor, demonstrate a robust, controllable system. The team observed current spikes similar to biological ion channels and fine-tuned pore behavior by adjusting chemical compositions. This innovation could advance single-molecule sensing, DNA sequencing, and neuromorphic computing through ultrasmall pore applications.
