Self‐Driving Laboratory Optimizes the Lower Critical Solution Temperature of Thermoresponsive Polymers

Advanced Intelligent Discovery, EarlyView.
A low‐cost, self‐driving laboratory is developed to democratize autonomous materials discovery. Using this "frugal twin" hardware architecture with Bayesian optimization, the platform rapidly converges to target lower critical solution temperature (LCST) values while self‐correcting from off‐target experiments, demonstrating an accessible route to data‐

Bistable Dual‐Responsive Azobenzene‐co‐PNIPAM Soft Microactuators via Two‐Photon Direct Laser Writing

Advanced Intelligent Systems, EarlyView.
This work shows the successful integration of intrinsic bistability into thermoresponsive soft microactuators, fabricated by two‐photon polymerization utilizing the (E)–(Z)‐isomerization of azobenzenes. The bistable behavior accounts for a reversible volume change of Azo_pNIPAM microactuators initiated by light irradiation, at constant ambient ...

Mimicking Life: Autonomous Oscillating Artificial Cilia Driven by Chemical Power

Advanced Intelligent Systems, EarlyView.
The synthesis and motion analysis of chemically actuated, individually autonomous artificial cilia are presented. Driven by an internal chemical reaction, the self‐driven individual cilia require no external stimuli. They undergo periodic oscillatory motion with a 3D beat pattern and exhibit chemotactic shifts, reminiscent of biological systems.

Tailored Dual Responsive Hybrid Gelatin Methacryloyl/Poly[2‐(Dimethylamino)Ethyl Methacrylate] Hydrogels for Efficient Ibuprofen Release in Topical Applications

Journal of Applied Polymer Science, EarlyView.
GelMA/DMAEMA hybrid hydrogels for release of ibuprofen. ABSTRACT In this study, biocompatible hydrogels intended for topical delivery of ibuprofen were synthesized from gelatin methacryloyl (GelMA) and 2‐(dimethylamino)ethyl methacrylate (DMAEMA) by varying their proportions. The impact of different GelMA and DMAEMA ratios was comprehensively evaluated
