S-scheme heterojunction-induced surface plasmon response

Journal of Materiomics
In this insight, we highlighted the emergence of a plasmonic response over ZnO/CuInS2 S-scheme heterojunction, which has been recently reported by Meng et al. (Adv. Mater. 2024, 36, 2406460).

Intimate Interaction Between Nucleic Acid and Conjugated Polymers in Organic Electrochemical Transistors Enables Ultrasensitive Biomarker Detection

Advanced Materials, EarlyView.
The intimate interaction between negatively charged RNA molecules and conjugated polymers in organic electrochemical transistors (OECTs) in aqueous electrolytes is investigated. It demonstrates that RNA binding reduces the volumetric capacitance of the polymer channel, enabling the development of an ultrasensitive biosensing platform capable of ...

Generation of Surface Plasmon Polariton Using Plasmonic Resonant Cavity Based on Microdisk Laser

IEEE Photonics Journal, 2011
We study the generation of surface plasmon polariton and its extraction efficiency from a microdisk-based plasmonic source to a metal-insulator-metal (MIM) waveguide.

BioEISense: A Microfluidic Platform for Real‐Time Monitoring of Staphylococcus aureus Biofilm Formation and the Efficacy of Antibiofilm Agents

Advanced Materials Interfaces, EarlyView.
BioEISense is a microfluidic device with integrated impedance sensors, for real‐time, label‐free monitoring of S. aureus biofilms. In this study, the biofilm culture conditions were optimized to support sensitive and reproducible detection of biofilm formation and eradication under dynamic flow‐through conditions. The system was also validated for both

Optical response of noble metal nanoparticles

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
The rich structure of surface plasmon modes localized in noble metal nanoparticles is explored by optical spectroscopy, spatially resolved electron energy-loss spectroscopy, and by electron beam-induced radiation emission.

Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning

Advanced Materials Interfaces, EarlyView.
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

Advanced Materials Interfaces, EarlyView.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.

Surface plasmons in terahertz metamaterials

Optics Express, 2008
We characterize terahertz metamaterials by applying apertureless near-field microscopy with a bandwidth that covers the entire spectral response of the structures. The observations agree with the interpretation of the fundamental mode of the metamaterial. But the high frequency resonance shows properties that deviate from the common interpretation.

Thermal Radiation Emission From 3D Graphene Networks

Advanced Materials Interfaces, EarlyView.
Three‐dimensional graphene networks are demonstrated as exceptional broadband thermal emitters, exhibiting high‐intensity, spectrally homogeneous emission and strong mechanical flexibility compared to conventional emitters like silicon carbide.
