Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

1.4% External Quantum Efficiency 988 nm Light Emitting Diode Based on Tin‐Lead Halide Perovskite

open access: yesAdvanced Materials, EarlyView.
The tin‐lead based halide perovskite film with the 3‐AMP passivate exhibits a significantly longer carrier lifetime of over 1 µs compared to the neat films (0.43 µs). The optimized tin‐lead halide perovskite LEDs show a single emission peak at 988 nm and an external quantum efficiency (EQE) of ≈1.4%.

Hydrogel‐Mediated Preservation of Live Tumor Explants for Drug Development in Peritoneal Metastases

open access: yesAdvanced Materials, EarlyView.
This study presents a hyaluronan‐based hydrogel platform preserving the native tumor microenvironment (morphology, tissue composition, histology) of patient‐derived explants from peritoneal metastases, enabling clinically relevant drug screening. Hydrogel properties such as stiffness and degradation are crucial for longer‐term histoculture.
