SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications

Small, EarlyView.
This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.

Interfacial Nano‐Pitting and In Situ Sulfate‐Directed Growth of Na2.85V2(PO4)2.85(SO4)0.15 Nanodots on MWCNT for Ultrafast Sodium‐Ion Storage

Small, EarlyView.
Ultracentrifugation‐assisted phosphate–sulfate treatment induces self‐limiting nano‐pitting on carbon nanotube surfaces, creating confined sites for in situ growth of Na2.85V2(PO4)2.85(SO4)0.15 nanodots. This embedded nanodot–carbon interface ensures strong electronic coupling and short ion pathways, enabling capacitor‐like sodium storage with ...

In Vitro Reconstruction of Axonal Heat Sensing with a Photothermal Nerve‐on‐a‐Chip

Small, EarlyView.
A photothermal nerve‐on‐a‐chip platform is presented that enables precise, localized heating of sensory axons with simultaneous electrical recording. The system reveals millisecond‐scale dynamics of heat‐evoked neural activity and provides a new approach to study how temperature‐dependent ion channel behavior is translated into axonal firing.

A flexible arched artificial photoreceptor constructed by photodeformable liquid crystal polymers and its application in vision restoration

Smart Molecules, EarlyView.
A flexible arched artificial photoreceptor with high stability and biocompatibility was fabricated by integrating liquid crystal polymers with polyvinylidene fluoride‐trifluoroethylene. This device exhibits robust photoelectric responses under low‐intensity illumination and demonstrates efficacy in restoring visual responses in blind rats following ...
