A Hydrophilic Hollow Microneedle Platform for Sampling Interstitial Fluid and On‐Site Biomarker Detection

Advanced Materials Technologies, EarlyView.
This study presents a superhydrophilic 3D‐printed hollow microneedle patch for continuous interstitial fluid (ISF) extraction and on‐patch biomarker sensing. Combining projection micro‐stereolithography and chemical vapor deposition, high‐resolution microneedles with enhanced wettability are fabricated, enabling passive ISF uptake without external ...

Polymer Dots Exhibiting Multi‐Resonant Thermally Activated Delayed Fluorescence for Cellular Imaging

Advanced Optical Materials, EarlyView.
By copolymerizing with a host material, a multiple resonance thermally activated delayed fluorescent (MR‐TADF) emitter quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) is successfully assembled into water‐dispersible polymer dots (Pdots). Photophysical measurements and multichannel fluorescence imaging studies show that the narrowband emission from the MR ...
