Conundrums of Localized Surface Plasmon Resonance Biosensors

Small, EarlyView.
Localized surface plasmon resonance (LSPR) biosensing faces fundamental conundrums arising from finite field decay lengths, environmental cross‐sensitivities, and batch variability. Competing surface, bulk, and electrostatic effects can induce red or blue spectral shifts, complicating quantification, reproducibility, and interpretation in complex or ...

Combined Foaming and Surface Structuring of Polymers With Supercritical Carbon Dioxide (scCO2) Applying an Incomplete Saturation Strategy

Journal of Applied Polymer Science, Volume 143, Issue 15, April 15, 2026.
Combined foaming and structuring of polymer samples by processing with supercritical CO2 leads to nano‐ and microstructured surfaces on top of perfectly white polymer sheets. ABSTRACT Supercritical carbon dioxide (scCO2) is a widely applied solvent utilized in many physical–chemical processes, including the foaming or structuring of polymers.

Nanomechanical Traceable Metrology of Vertically Aligned Silicon and Germanium Nanowires by Nanoindentation

Proceedings, 2017
Silicon and germanium pillar structures (i.e., micro- and nanowires) were fabricated by a top-down approach including nanoimprint lithography and cryogenic dry etching. Various etching parameters were tested to ensure a reliable fabrication process.

Engineering Chiroptical Interactions through Integrating Plasmonic Arrays with Cholesteric Nanocellulose

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
In this study, we demonstrate how the combination of plant‐based cellulose and gold nanoparticle lines produces robust, tunable chiral light control in composite films. The resulting plasmonic cellulose composite exhibits a strong plasmonic CD at the surface lattice resonance, along with an inversion of chiroptical response upon reversing the ...

High‐Brightness, Wide‐Gamut, and High‐Resolution Structural Colors via Ultrafast Laser Oxidation of Ti/TiO2 Films

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Ultrafast laser writing on titanium (Ti)–titanium dioxide (TiO2)–Ti sandwich films triggers controllable oxidation (〉200 nm) to create vivid, durable structural colors. The colors reach 〉 80% of the standard RGB (sRGB) gamut, up to 60% peak reflectance, and 30,000 dots per inch (DPI) resolution for art and anti‐counterfeiting.

Periodic and Statistically Distributed Surface Texturing of Surface‐Enhanced Raman Spectroscopy (SERS) Sensors with Spatially Selective Signal Mapping

Advanced Physics Research, Volume 5, Issue 3, March 2026.
Molecular fingerprinting for the detection of biomolecules is highly sensitive and noninvasive through the surface‐enhanced Raman scattering (SERS) effect. This is a report on the commercially competitive performance of gold‐coated periodic structures and black Si (aperiodic) nanostructures as plasmonic SERS substrates.

Scissorable Piezoelectric Nanogenerators Comprising Flexible Micrograting Electrodes Interconnected by Laterally Aligned ZnO Nanowires for Size‐Customizable Devices

EcoMat, Volume 8, Issue 3, March 2026.
A “scissorable” piezoelectric nanogenerator (SCIPENG) comprising flexible micrograting electrodes laterally interconnected by ZnO nanowires is developed. The SCIPENG device can be easily resized simply by using scissors without compromising performance, offering predictable scaling of output voltage and current.

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.
