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.

The Equivalence of Microlens and Metalens for THz High Spatial‐Spectral Resolution Hyperspectral Imaging with a Large Field of View

open access: yesAdvanced Optical Materials, EarlyView.
An ultrabroadband THz microlens with high resolution is presented and fabricated via commercially available 3D printing by transforming the phase profile into a thickness profile. The proposed method enables high‐fidelity THz hyperspectral imaging with high spatial and spectral resolution, representing a cost‐effective and reliable solution.
