Low impedance and highly transparent microelectrode arrays (MEA) for in vitro neuron electrical activity probing

Anna Susloparova, Sophie Halliez, Séverine Begard, Morvane Colin, Luc Buée, Sébastien Pecqueur, F. Alibart, V. Thomy, S. Arscott, Emiliano Pallecchi, Yannick Coffinier

In this study, we present the microfabrication and characterization of a transparent microelectrode array (MEA) system based on PEDOT:PSS for electrophysiology. The influence of the PEDOT:PSS electrode dimensions on the impedance was investigated and the stability over time under physiological…

Any neuron can perform linearly non-separable computations

Romain Cazé

Multiple studies have shown how dendrites enable some neurons to perform linearly non-separable computations. These works focus on cells with an extended dendritic arbor where voltage can vary independently, turning dendritic branches into local non-linear subunits. However, these studies leave a…

Experimental and theoretical study of group delay times and density of states in one-dimensional photonic circuit

S. Khattou, M. Amrani, A. Mouadili, E.H. El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

We present a comparative study of density of states (DOS) and group delay times for a one-dimensional (1D) coaxial photonic crystal made of N cells attached horizontally along a waveguide. Using the interface response theory of continuous media, we derive exact analytical expressions relating the…

Experimental full wavefield reconstruction and band diagram analysis in a single-phase phononic plate with internal resonators

N. Kherraz, M. Radzieński, M. Mazzotti, P. Kudela, F. Bosia, A. S. Gliozzi, D. Misseroni, N. M. Pugno, W. Ostachowicz, M. Miniaci

Research on phononic crystal architectures has produced many interesting designs in the past years, with useful wave manipulation properties. However, not all of the proposed designs can lead to convenient realizations for practical applications, and only a limited number of them have actually been…

Enhanced phonon-plasmon interaction in film-coupled dimer nanoridges mediated by surface acoustic waves

Adnane Noual, Rock Akiki, Gaëtan Lévêque, Yan Pennec, Bahram Djafari-Rouhani

The interaction between phonons and localized plasmons in coupled nanoparticles can be exploited both for modulating the scattered electromagnetic field and the understanding of the mechanical vibrations at nanoscale. In this paper, we demonstrate by numerical analysis an enhanced optomechanical…

DNA aptamers block the receptor binding domain at the spike protein of SARS-CoV-2

Fabrizio Cleri, Marc Lensink, Ralf Blossey

DNA aptamers are versatile molecular species obtained by the folding of short single-stranded nucleotide sequences, with highly specific recognition capabilities against proteins. Here we test the ability of DNA aptamers to interact with the spike (S-)protein of the SARS-CoV-2 viral capsid. The S-…

AIDX: Adaptive Inference Scheme to Mitigate State-Drift in Memristive VMM Accelerators

Tony Liu, Amirali Amirsoleimani, F. Alibart, Serge Ecoffey, Dominique Drouin, Roman Genov

An adaptive inference method for crossbar (AIDX) is presented based on an optimization scheme for adjusting the duration and amplitude of input voltage pulses. AIDX minimizes the long-term effects of memristance drift on artificial neural network accuracy. The sub-threshold behavior of memristor…
