Hydrogel microwells with light-controlled reversible closure
Qifei Ma, David Urban, Stefano Gabetti +8
We present a light-responsive hydrogel nanocomposite engineered into arrays of micrometer-scale wells that can be selectively and sequentially closed and re-opened via laser illumi…
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…
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…
Plasmonic Janus particles: A perspective on optical manipulation and biomedical applications
Alemayehu Nana Koya, Anastasiia Sapunova, Nageswar Reddy Sanamreddy +8
The compositional asymmetry of Janus micro- and nanoparticles gives unprecedented opportunities to manipulate such composite particles with different stimuli to achieve enhanced op…
