Research

We are a research team within the Institute of Electronics and Systems in Montpellier, France. We are developping Microfluidics, Microsystems and Biophotonics to perform experiments on cells in vitro. We focus on neuroscience, single cell analysis via physical trapping but also in blood physics and engineering of trapped particles in optical tweezers. We have a specialty in developping microfluidics with sensors and actuators.

Microfluidic systems for neuroscience

Compartmentalized microfluidics are devices that allow the in-vitro reconstitution of neuronal circuits using primary cultures of different neuronal populations. We design and build these devices for the reconstruction of cortico-cortical networks in which each compartment (presynaptic, synaptic and postsynaptic) is identified (space compartmentalization) and in which the progression from axonal growth to synapse regulation is controlled (time compartmentalization). The device consists of two opposite neuronal chambers that communicate via an intermediate synaptic chamber through long microchannels on one side (to select axons only) and short ones on the other side (to allow dendrites to reach the synaptic chamber). This configuration allows the reconstruction of axono-dendritic contacts between two cortical populations such as those found between cortical layers in vivo. In addition we also developp Neuro muscular junctions on chip and we integrate specific microelectrode arrays to stimulate and record the electrical activities of cells.

Neuron Light Interactions

The optical stimulation of neurons from pulsed infrared lasers has appeared over the last years as an alternative to classical electric stimulations based on conventional electrodes. Laser stimulation could provide a better spatial selectivity allowing single-cell stimulation without prerequisite contact. In this work we present relevant physical characteristics of a non-lethal stimulation of cultured mouse vestibular and retinal ganglion neurons by single infrared laser pulses.

Trapped Particles Nano engineering

In collaboration with Francesco PEDACI's group : Single-molecule angular dynamics group at CBS, Montpellier

Optical tweezers are a scientific instrument that allow particles with an optical index different from the liquid medium in which they are immersed to be trapped in the waist of a laser beam. This technique, invented by Arthur Ashkin and for which he won the Nobel Prize in 2018, allows many biophysical experiments to be carried out using trapped particles as actuators of unique molecules. In order to broaden the range of biophysics experiments, we are working with Francesco Pedaci team at CBS Montpellier to develop specific particles that allow functions to be added to them and broader problems to be addressed. This is why we are developing collective microfabrication processes that produce millions of particles with specific dimensions and shapes for optical tweezers experiments. The first work we carried out concerned the rotation of cylindrical particles trapped under optical tweezers. By micromachining solid quartz, that is birefringent, we have designed conical cylindrical particles that can be driven in rotation by the effect of a rotating polarization of the trapping beam. The second part of our particle engineering work consisted in developing cylindrical particles with refined tips to implement a near-field imaging technique called Photonic Force Microscopy.

Hemophysics

In collaboration with Manouk ABKARIAN's group : hemophysique at CBS, Montpellier

Blood is a non-Newtonian complex fluid consisting of a dense suspension of cells in plasma. Blood is also a shear-thinning, it means that its viscosity drops when the shear rate increases. In order to study hemophysics, and in particular how blood flows into vascular networks, we are working at the development of microfluidic based experiments to investigate the behaviour of blood in different shear rate regimes, vessel topology using replicas of blood vasculature. We also have been working at the development of an ultrasonic pulse echo device that can sense the liquid/gel/solid transition of sessile droplet evaporating. This research activity is funded by the Labex NUMEV within the frame of the Rheoblood project.
