Over Tenfold Increase in Current Amplification Due to Anisotropic Polymer Chain Alignment in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
How to boost the IDS output of an OECT? Anisotropic polymer alignment along the channel direction enables a 13‐fold increase in IDS. Such channel engineering opens the door to unprecedented signal amplification (here gmL/Wd = 2 580 S cm−1 with a PBTTT‐backbone bearing single‐ether side chains), faster ON/OFF switching, and improved stability for the ...

Intrinsically‐Stretchable and Patternable Quantum Dot Color Conversion Layers for Stretchable Displays in Robotic Skin and Wearable Electronics

Advanced Materials, EarlyView.
Intrinsically‐stretchable, heavy‐metal‐free quantum dot color conversion layers are produced via a versatile crosslinking strategy. The color conversion layers exhibit minimal backlight leakage under mechanical strain, support high‐resolution patterning, and integrate seamlessly with micro‐light‐emitting diodes. Their incorporation in haptic‐responsive

Polyanhydride‐Based Microparticles for Programmable Pulsatile Release of Diphtheria Toxoid (DT) for Single‐Injection Self‐Boosting Vaccines

Advanced Materials, EarlyView.
This study presents a polyanhydride‐based delivery platform for single‐injection, self‐boosting vaccines. The system enables programmable, pulsatile release of diphtheria toxoid with high antigen recovery and is guided by machine learning for tunability. In vivo results show immune responses comparable to multi‐dose regimens, highlighting its potential
