Nanoelectronic Detection of Opioids: Machine Learning‐Powered Screening With Carbon Nanotube Field‐Effect Transistor Sensor Array

Small, EarlyView.
A carbon nanotube field‐effect transistor (NTFET) sensor array is constructed to screen different opioids with machine learning models. Codeine, fentanyl, hydrocodone, and morphine are tested using the NTFET sensor array and classified with both conventional supervised learning models and deep learning models.

Remote‐Controlled Release of Nitric Oxide by Plasmonic Waveguide Coated With Metal–Organic Frameworks

Small, EarlyView.
Remote‐controlled intracellular delivery is achieved using a plasmonic waveguide coated with a photoresponsive NO‐releasing MOF. Surface plasmon polariton propagation remotely induces photocleavage and localized nitric oxide release in a target single live cell without direct light exposure, while biological relevance is demonstrated through transient ...

Active control of Lubricant Flow Using Dielectrophoresis and Its Effect on Friction Reduction

Tribology Online, 2023
With the increasing demand for active friction control, we newly proposed to use dielectrophoresis to change the flow of PG-droplet-containing PAO4 to reduce the friction coefficient. The friction result with a 1-mm roller shows 20% reduction in friction
