Plasmonically Enhanced Microarray Immunoassay for High‐Sensitivity Monitoring of Heart Failure

Advanced Materials, EarlyView.
A novel plasmonically enhanced PE‐D4 assay combines nanopatch antennas with a microarray immunoassay for the detection of heart failure biomarkers NT‐proBNP, NGAL, and galectin‐3 in complex biological samples. Plasmonic amplification substantially enhances fluorescence signals, enabling sensitive biomarker quantification with a low‐cost smartphone ...

A U‐shaped Microfluidic Platform for Culturing Vascularized Colorectal Cancer Spheroids Reveals Tumor–Endothelial Crosstalk and Invasion‐Associated Remodeling

Advanced Materials Technologies, EarlyView.
A closed U‐shaped microfluidic platform symmetrically embeds a single, size‐controlled HT29 colorectal cancer spheroid within a GFP‐HUVEC‐laden fibrin matrix. HT29 spheroids are associated with hyper‐branched endothelial network remodeling, while vascularized co‐culture is accompanied by anisotropic protrusive growth and EMT‐like marker changes in the ...

Ultrafast multi-focus 3-D nano-fabrication based on two-photon polymerization

Nature Communications, 2019
Two photon polymerization (TPP) allows nanofabrication of three dimensional objects with complex geometries, but is considered to be slow with a limited fabrication rate.

Photoluminescence Reshaping via Structural Confinement and Local Density of Optical States Control in Ir(III)‐Doped Biodegradable Metasurfaces

Advanced Materials Technologies, EarlyView.
Phosphorescent biodegradable metasurface showing vibronic selection and spectral photoluminescence narrowing. Anti‐correlation between experimental LDOS and measured lifetimes. ABSTRACT Metasurfaces incorporating phosphorescent emitters offer a route to engineer radiative and vibronic processes beyond chemical design.

Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites

Advanced Materials Technologies, EarlyView.
Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration

In-Line Defect Detection on Painted Surfaces in Motion Using Template Matching

Sensors
Quality control of exterior surfaces, particularly painted finishes, is a determining factor in the perceived quality of a device, which impacts the purchasing decision. Automating this process reduces potential human mistakes and improves efficiency. In

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

Advanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Maskless photolithography for micro- and nanofabrication

Moore and More
As a micro- and nanofabrication technique, maskless photolithography (MPL) eliminates static physical masks and instead utilizes computer-controlled light sources and optical systems to directly generate patterns.
