Ag‐Cu Nanoarchitecture for Enhanced LSPR Absorption: the Role of Surface Roughness and near‐field Interactions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the plasmonic properties and biosensing capabilities of a nanocomposite incorporating Cu and Ag nanoparticles for detecting anti‐DbpA antibodies associated with Lyme disease. The enhanced LSPR response is explained through FDTD simulations of Cu–Ag near‐field interactions and increased surface roughness.

IR Spectroscopic Studies on Water Confined in an Isoreticular MOF Series–Influence of the Metal and Linker Functionality

open access: yesAdvanced Materials Interfaces, EarlyView.
Mono‐ and bimetallic isoreticular MOF‐74 analogs with different ratios of Mg2+ and Ni2+ and linkers of different sizes and functionalities are synthesized and loaded with water. With the help of IR spectroscopy, semiquantitative conclusions are drawn regarding the prevalence of differently ordered water species in dependence on the confinement and ...

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

open access: yesAdvanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Mie‐Resonant Metasurfaces with Controlled Silicon Oxidation in Electron‐Beam Deposition

open access: yesAdvanced Materials Interfaces, EarlyView.
Electron‐beam deposition is optimized to prevent silicon oxidation by controlling chamber pressure and deposition rate, yielding refractive index values comparable to other methods. This tunability enables precise control of optical properties. Mie‐resonant metasurfaces exhibit strong, tunable collective resonances, allowing the fabrication of silicon ...
