Point-of-Care Applicability of Graphene-Based Field Effect Transistors upon Modification with a Pyrene-Tagged Antifouling Copolymer: Application for cTnI Sensing in Blood

Rupali Bagale, Manova Santhosh Yesupatham, Abdellah Hambli, Subhankar Sahu, Christophe Ritzenthaler, Mandana Amiri, Sandro Spagnolo, Anna Kálosi, Francesco Basini, Henri Happy, Rabah Boukherroub, Wolfgang Knoll, Tibor Hianik, Eva Majková, Peter Šiffalovič, Roberto Corradini, David Montaigne, Eloise Woitrain, Adriana Hvizdošová Annušová, Sabine Szunerits

Field-effect transistors (FETs) are an integrated part of various electronic products and play an irreplaceable role in modern-day bioelectronics and biosensors. The electronic performance of FET-based sensors is intrinsically correlated with the choice of the sensing layer, with graphene being one…

Low-temperature cotunneling electron transport in photoswitchable molecule-nanoparticle networks.

Yannick Viero, David Guérin, Dominique Vuillaume

We report the temperature-dependent (4.2 - 300 K) electron transport properties (current-voltage) of photo-switchable two-dimensional arrays of gold nanoparticles (10 nm in diameter) functionalized by azobenzene derivatives. Under UV-light irradiation at 4.2 K, the azobenzene moieties are switched…

Advancing medical question answering with a knowledge embedding transformer

Xiang Zhu, Mustaqeem Khan, Abdelmalik Taleb-Ahmed, Alice Othmani

Efficient medical question answering is essential for better patient care. Despite progress since Eliza (1966), even advanced LLMs (e.g., GPT-4) struggle with medical data. This study presents a system combining knowledge embedding and transformers. It includes a knowledge understanding layer and…

Spikeless Dielectric Waveguides for 600-GHz-Band Terahertz Communications

Nguyen Ngo, Guillaume Ducournau, Weijie Gao, Hadjer Nihel Khelil, Rita Younes, Abdu Subahan, Pascal Szriftgiser, Hidemasa Yamane, Yoshiharu Yamada, Shuichi Murakami, Masayuki Fujita

We propose a spikeless dielectric waveguide that achieves robust coupling between a silicon waveguide and a metallic hollow waveguide without relying on conventional tapered transitions. The waveguide has a large fractional bandwidth of 61% (330–620 GHz) with an average coupling efficiency of –1.7…

Terahertz Far-Field Measurements of a Meta-Atom Composed of Concentric Disk and Ring

Surya Revanth Ayyagari, Simonas Indrišiūnas, Daniil Pashnev, Guillaume Ducournau, Irmantas Kašalynas

Resonance behavior of a single meta-atom composed of concentric disk and ring with inter-bridges embedded in a free-standing metal film was investigated experimentally and numerically. The meta-atom was integrated either in square or in circular aperture aiming to exhibit transparency at the…

High bandwidth THz polarization modulation of Inverse Spin Hall emitters exploiting Spin Reorientation Transition of an anisotropic CoFeB layer

Geoffrey Lezier, Pierre Kolejak, Filip Gaizura, Jean-François Lampin, Nicolas Tiercelin, Mathias Vanwolleghem

We demonstrate an efficient and simple modulation of the polarization in Inverse Spin Hall Effect spintronic Terahertz Emitters (ISHE STE), by rapid switching of the magnetization using a high-frequency magnetic field, enhanced by field induced Spin Reorientation Transition (SRT). The instability…
