Full textThe charges at liquid/solid interfaces are a key element for both understanding and exploiting the electrokinetic phenomena in micro/nanofluidics. The manuscript of my Ph.D thesis is dedicated to these phenomena, which is divided into three main parts: Above all, a simple overview of charges at the liquid/solid interface is proposed. Then, several common methods for measuring the zeta potential at the liquid/solid interface are described. Next, various effective methods to preconcentrate the biological molecules is presented with the help of the surface charges. Secondly, the streaming current, which is a standard method to measure the zeta potential in our laboratory, is detailed. It contains the upgrade of the experimental setup from the previous version and the development of new protocols, which improve dramatically the stabilization and the reproducibility of the measurements. In addition, an original biological sensor is briefly presented based on these advancements. Lastly, in the final part, we describe a method which is primitively utilised in the fabrication of Micro-Nano-Micro fluidic system. Based on this system, some favorable preconcentration results is obtained. Moreover, numerical simulations are presented to prove the originality of our work

Full textThe modern infrared cameras allow the measurement of thermal fields and their temporal evolution. Infrared images processing is suitable to analyze the thermal signature of moving objects or fluid flows. In this context, we made the study of three different experiments. The first one is relative to infrared tracking of randomly moving balls and then estimate their thermal exchanges with the environment by the estimation of some characteristic time. In the second case we made a comparison between two fluids which flow inside a microchannel in order to determine the relative changes of thermal properties. The last application was to estimate a thermal diffusivity field with a mobile heat source

Full textThe current will of reducing environment and human hazards has led the scientists to imagine new solutions for nuclear waste reprocessing. Miniaturized online chemical analysis of industrial processes has in particular an important role to play to reduce effluent volumes, response times and costs. In this context, we present the design, fabrication and characterization of an integrated spectrophotometric sensor on glass for chemical analysis of radioactive cations. The device is called a ―nanochannel waveguide‖ and is fabricated by reactive ion etching and ion exchange on glass. It is made of two borosilicate glass wafers bonded together. The first one contains a strip core and the second one a (100 ±10) nm deep nanochannel and a slab core. It allows the propagation of a hybrid mode, optimizing the fluid/guide wave interaction on a large wavelength range. Spectrometric measurements of a neodymium nitrate in nitric acid (pH 2) followed by statistical treatment have led to a limit of detection in terms of absorption coefficient of (3.7 ± 0.9) x 10-3 cm-1 for a device length of (3.70 ± 0.05) cm and fluid volume as low as (7 ± 3) nL. A structure allowing to increase the interaction length and therefore further decrease the detection limit has been proposed as an outlook of this work, and a preliminary study for use in a nuclear environment has been performed

Full textNanofluidics marks the emergence of promising new technologies for the production of blue energies. These renewable energies with low environmental impact harness the entropy of mixing of fresh and salt water, for example at the estuary of a river, to generate electricity. Diffusio-osmosis (which flow is associated with diffusiophoretic displacement) is a serious candidate for the generation of electric currents. This phenomenon stems from osmotic effects inside the nanopores of the membrane and its intensity is directly linked to the surface charge of the material. Waterionic liquid thermoresponsive binary mixtures are an alternative to rivers and oceans to generate a salt gradient. The monophasic or biphasic state of the mixture is controlled by temperature; in the present case the LCST nature of the fluid induces a demixing by heating. Our work focuses on the phase separation of the mixture in a microfluidic cavity, where we show that a confinement or temperature gradient is a precious help to selectively isolate the two phases. We also measure the intensity of diffusio-osmotic currents with these solutions of ionic liquids in single nanopores and multi-pore membranes

Full textOwing to their unique physico-chemical properties, colloidal nanoparticles are building blocks for the creation of plentiful innovative devices. In order to make easier their characterization and to incorporate them into functional nano-devices, it is necessary to perfectly control their directed assemblies onto solid surfaces. In this context, this thesis’ purpose is to simultaneously better understand and optimize the nanoxerography method, which allows electrostatic and selective directing assemblies of nanoparticles onto charged patterns. After an optimization of the nanoxerography process, three specific problematics have been addressed: (1) micron-sized particles assembly. The combined use of numerical simulations and experiments enabled to unveil the key parameters involved in micron-sized particles assembly and to expend the particle size range foreseeable for an assembly by nanoxerography (factor 100). (2) the 3D assembly analysis. The influence of diverse parameters on the 3D assembly of luminescent model nanoparticles was quantified by using a new assembly protocol. The results gave the generic key criterions for the 3D assembly of colloids by nanoxerography. (3) directed assembly of nanogels sensitive to an external environmental stimulus. The use of an optimized protocol allowed elaborating nanogels assemblies interactive with their environment and to sort these nanoparticles onto the same surface
