Bilateral SERS‐Microneedle Patch for Co‐Diagnosis of Diabetes Mellitus and Tuberculosis Comorbidity

Advanced Science, EarlyView.
Our study introduced a U@mP@Au‐mediated bilateral SERS‐microneedle patch for analyzing glucose levels from ISF and sensitively detecting TB biomarkers from sputum, respectively. This integrated dual‐analyte detecting platform can be used for co‐diagnosis of diabetes mellitus (DM) and tuberculosis (TB) comorbidity, which was demonstrated in ex vivo ...

Geometry‐Controlled Assembly of Self‐Standing Nanorods With Undisturbed Plasmonics

Advanced Science, EarlyView.
This study reports a geometry‐driven assembly strategy to vertically align Au@Ag core–shell nanorods on PS beads. This well‐defined architecture enables the preservation of the intrinsic optical response of individual nanorods. Thus, demonstrate a highly reproducible SERS enhancement with exceptional uniformity.

Imaging Electric Polarization Switching in Multilayer Graphene

Advanced Science, EarlyView.
Domain wall sliding‐induced electric polarization switching is directly observed for the first time in multilayer graphene, enabled by a novel optical readout method. The polarization switching is realized upon application of global and local electric fields, and mechanical forces between neighboring polar domains of opposite out‐of‐plane polarizations
