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 ...

Tuning the stimuli-responsive properties of poly(ionic liquid)s [PDF]

, 2015
Poly(Ionic Liquid)s (PILs) are a class of ionic liquids that feature polymerizable groups in either the cation, the anion or both. PILs can be used in various applications, including solid ion conductors or for CO2 absorption.

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
