Programmable Microscale Actuation of Hydrogels With Tunable Response via Printing on Particles
Advanced Materials Technologies, EarlyView.We fabricate microscale hydrogels with precisely tunable phase transition temperatures (23–60 °C) by particle‐templated two‐photon polymerization using chemically tailored inks. Multi‐material printing enables stepwise thermal actuation through sequential volume changes at distinct VPTTs, while pH‐dependent hysteresis drives anisotropic actuation with ...

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...

Interfacial Assembly of Dye‐Doped Microparticles Driven by Combined Optical and Non‐Optical Forces
Advanced Optical Materials, EarlyView.Optical trapping controls nano‐ and microparticle assembly using various forces, including absorption for photoexcitable resonant molecules. This study demonstrates photoexcitation‐mediated assembly, forming hexagonal‐close‐packed structures at the air/solution interface.

Excitation of Quasi‐Bound States in the Continuum With Focused Radially Polarized Beams
Advanced Optical Materials, EarlyView.This work presents an innovative strategy for exciting symmetry‐protected quasi‐bound states in the continuum in periodic arrays of nanostructures using focused radially polarized light beams. Compared to excitation with a tilted plane wave, this approach can achieve both higher quality factors and stronger optical responses.

Advanced Optical Materials, EarlyView.A label‐free plasmonic nanosensor platform is presented based on single gold nanorods for the nanometric characterization of lipid interfaces. By correlating optical scattering signals with membrane packing and refractive index, this approach enables the detection of gel‐to‐fluid transitions in lipid interfaces, offering a robust, high‐resolution ...
