Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning

open access: yesAdvanced Materials Interfaces, EarlyView.
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as

Metal‐Enhanced Charge Transport and its Mechanism in Atomically Precise Ruthenium Single‐Molecule Devices

open access: yesAdvanced Science, EarlyView.
An atomically precise platform was developed for investigating single‐molecule charge transport. This innovative platform enables the creation of highly uniform molecular devices using ruthenium‐based molecules. It reveals a significant enhancement in molecular conductance due to the metallic ruthenium center and a unique barrier‐lowering effect during
