Optimization of surface treatment on MEMS probes for single-cell capture and release

Kensaku Hayashi, Momoko Kumemura, Shohei Kaneda, Vivek Menon, Laurent Jalabert, Saeko Tachikawa, Mehmet Tarhan, Teruo Fujii, Beomjoon Kim, Hiroyuki Fujita

Micro-electromechanical systems (MEMS) tweezers developed for the trapping and characterization of bio molecules such as DNA are also capable of cell handling, which will enable further application involving single cell characterization. However, cellular adhesion to Si tweezers surfaces can…

Chapter 7 - Two-dimensional magnonic crystals

L. Dobrzynski, Housni Al-Wahsh, Abdellatif Akjouj, Yan Pennec, Bahram Djafari-Rouhani

This chapter presents a short tutorial introduction to the theoretical investigations of two-dimensional inhomogeneous magnetic media. Simple examples are presented for the calculation of the spin-wave spectra of two-dimensional composite materials consisting of periodic square arrays of parallel…

Numerical Modelling of Vibration Characteristics of a Partially Metallized Micro Electromechanical System Resonator Disc

Ismail Naciri, Abdessamad Rguiti, Lahoucine Elmaimouni, Jean-Etienne Lefebvre, Faniry Emilson Ratolojanahary, J. G. Yu, Youssef Belkassmi, Ali El Moussati

In this paper, we report an extension of a polynomial and numerical vibrational characterization of an annular piezoelectric disc resonator partially covered with electrodes. The three governing partial differential equations of motion are solved to provide the frequency response of the…

Thermal Stability of Oleate‐Stabilized Gd2O2S Nanoplates in Inert and Oxidizing Atmospheres

Clément Larquet, D. Hourlier, Anh-Minh Nguyen, Almudena Torres-Pardo, Andrea Gauzzi, Clément Sanchez, Sophie Carenco

Capping ligands play an important role in the chemistry of nanoparticles synthesized with organic surfactants. This is relevant to a number of device applications where heating may cause major modifications of crystalline nanoparticles including amorphization, surface rearrangements or sintering.…

On a generic theory of the organic electrochemical transistor dynamics

Vasileios Athanasiou, Sébastien Pecqueur, Dominique Vuillaume, Zoran Konkoli

In the recent years, the organic electrochemical transistors (OECT) have attracted considerable attention for biosensing applications due to the biocompatibility of their materials and their low operating voltages. Upon exposure to an electrolyte, the drain current becomes ion-dependent. This can…

Elastic wave propagation in smooth and wrinkled stratified polymer films

M Hesami, A. Gueddida, N Gomopoulos, H S Dehsari, K Asadi, S Rudykh, H-J Butt, Bahram Djafari-Rouhani, G Fytas

Periodic materials with sub-micrometer characteristic length scale can provide means for control of propagation of hypersonic phonons. In addition to propagation stopbands for the acoustic phonons, distinct dispersive modes can reveal specific thermal and mechanical behavior under confinement. Here…

Blocking bacterial entry at the adhesion step reveals dynamic recruitment of membrane and cytosolic probes

Yann Ciczora, Sébastien Janel, Magali Soyer, Michka Popoff, Elisabeth Werkmeister, Frank Lafont

Background: Bacterial invasion covers two steps: adhesion and entry per se. The cell signalling response is triggered upon pathogen interaction at the cell surface. This response continues when the pathogen is internalised. It is likely that these two steps activate different molecular machineries…

Exploring Light-Sensitive Nanocarriers for Simultaneous Triggered Antibiotic Release and Disruption of Biofilms Upon Generation of Laser-Induced Vapor Nanobubbles

Eline Teirlinck, Alexandre Barras, Jing Liu, Juan Andrés A Fraire, Tatu Lajunen, Ranhua Xiong, Katrien Forier, Chengnan Li, Arto Urtti, Rabah Boukherroub, Sabine Szunerits, Stefaan C de Smedt, Tom Coenye, Kevin Braeckmans

Impaired penetration of antibiotics through bacterial biofilms is one of the reasons for failure of antimicrobial therapy. Hindered drug diffusion is caused on the one hand by interactions with the sticky biofilm matrix and on the other hand by the fact that bacterial cells are organized in densely…

Chapter 6 - One-dimensional magnonic crystals

L. Dobrzynski, Abdellatif Akjouj, Housni Al-Wahsh, Bahram Djafari-Rouhani

This chapter presents examples of bulk and surface magnons of one-dimensional magnonic crystals, called also superlattices. The such man-made crystals considered here are grown out of semiinfinite stacks of two and also three different ferromagnetic slabs. Each slab is modeled by a simple cubic…

Ferroelectric multiple-valued logic units

Igor A. Luk'Yanchuk, Elena Zaitseva, Vitaly Levashenko, Miroslav Kvassay, Svitlana Kondovych, Yuri Tikhonov, Laurent Baudry, Anna Razumnaya

Employing many-valued logic (MVL) data processing allows to dramatically increase the performance of computing circuits. Here we propose to employ ferroelectrics for the material implementation of MVL units basing on their ability to pin the polarization as a sequence of multi-stable states. Two…
