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…
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…
Reconfigurable Magnetic Nanopore Platform for Selective Trapping
Nageswar Reddy Sanamreddy, Jeanne Maunier, Malavika Kayyil Veedu +5
Solid-state nanopores offer a powerful platform for nanoscale analysis of individual analytes, including biomolecules and functionalized nanoparticles, by confining them within a p…
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…
DNA-Origami-Assembled Rhodium Nanoantennas for Deep-UV Label-Free Single-Protein Detection
Nicco Corduri, Malavika Kayyil Veedu, Yifan Yu +6
Nanoparticles of plasmonic metals have significantly to the development of spectroscopic techniques, enabling strong confinement of electromagnetic fields at the nanoscale and corr…
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…
