Microneedles From Shape‐Preserving Crosslinked Poly(Vinyl Alcohol) Hydrogels: Minimising Interference in Transdermal Proteomics

open access: yesAdvanced Materials Technologies, EarlyView.
Hydrogel‐forming microneedle patches are developed using shape‐preserving PVA‐PVP hydrogels, with and without chitosan, for minimally invasive transdermal protein biomarker sampling. The optimised patches enable efficient interstitial fluid uptake and proteomic analysis, while minimising interference.

Programmable Microscale Actuation of Hydrogels With Tunable Response via Printing on Particles

open access: yesAdvanced 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 ...

A Modular Microfluidic System to Generate Gradient Hydrogels with Simple‐to‐Complex Stiffness Profiles for Mechanobiology

open access: yesAdvanced Materials Technologies, EarlyView.
This work introduces a universal approach for fabricating stiffness gradient hydrogels with diverse stiffness ranges and gradient profiles. Gradient formation is achieved by precisely controlling the thermal landscape within a microfluidic system, which drives thermophoretic redistribution of precursor components in solution.

A Multi‐Resonant Tunable Fabry‐Pérot Cavity for High Throughput Spectral Imaging

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study introduces a multi‐resonant tunable Fabry‐Pérot filter for high throughput spectral imaging. With a spectral resolution of 10 nm and a switching time of 23 ms, this compact and low‐cost device possesses better spectral imaging accuracy in poor light conditions while maintaining over six times higher optical throughput than standard liquid ...
