Voltage-Controlled Phosphate Precipitation Gating in Solid-State Nanopore Memristors
Weihong Wang, German Lanzavecchia, Ali Douaki +9
Nanofluidic memristors preserve a record of electrical activity via ion migration and alterations in conductance that depend on the history of the device s state. These characteris…
Sel-assembled Rhodium Nanoantennas for Single-Protein UV SERS
Yanqiu Zou, Nicco Corduri, Francesco DAmico +11
Surface-enhanced Raman scattering (SERS) provides critical insights into analyte structure, dynamic processes, and intermolecular interactions at the single-molecule level. By expl…
Plasmonic nanopore to monitor in-pore chemistry
Weihong Wang, Shukun Weng, Ali Douaki +8
In solid-state nanopores, achieving reliable control over pore aperture opening and closing (gating) remains a major challenge. Gating can be driven by the applied voltage involvin…
Probing Electro-Magnetic Field Enhancement in 3D Plasmonic Nanopores Using DNA-PAINT and Nanorulers
German Lanzavecchia, Anastasiia Sapunova, Alan Szalai +6
Plasmonic nanopores combine nanofluidic confinement with electromagnetic field enhancement, enabling optical interrogation of single molecules in sub-wavelength volumes. Yet, direc…
UV-SERS monitoring of plasmons photodegradation of biomolecules on Aluminum platforms decorated with Rhodium nanoparticles
Yanqiu Zou, Luca Mattarozzi, Huaizhou Jin +13
In the search for novel nanostructured materials for UV plasmonics a limited number of choices can be done. Materials such as aluminum, rhodium, gallium and few others can be used.…
Layered Bimetal Nanoporous Platforms for SERS Sensing
Yanqiu Zou, Anastasiia Sapunova, Tommaso Giovannini +15
Nanoporous metals are extensively investigated as platforms for applications in plasmonics. They present high surface areas and strong local electric fields that can be tuned at di…
