In this work we report on the design, microfabrication and analytical performances of a new electrochemical sensor array (ESA) which allows for first time simultaneous amperometric detection nitric oxide (NO) peroxynitrite (ONOO−), two biologically relevant molecules. The on-chip device includes individually addressable sets gold ultramicroelectrodes (UMEs) 50 µm diameter, Ag/AgCl reference electrode counter electrode. electrodes are separated into groups; each has one electrode, 110 UMEs...
A simple and versatile methodology has been developed for the simultaneous measurement of multiple concentration profiles colourants in transparent microfluidic systems, using a conventional transmitted light microscope, digital colour (RGB) camera numerical image processing combined with multicomponent analysis. Rigorous application Beer–Lambert law would require monochromatic probe conditions, but spite broad spectral bandwidths three channels camera, linear relation between measured...
Growing interest in oceanology and oceanography has made it possible to determine the fundamental role of oceans sustaining life on Earth, discover that aquatic environments offer a rich biodiversity privileged habitat for many species. Aquatic also contribute economies countries through fishing, aquaculture, coastal tourism, they are major source food world’s population. Nevertheless, presence pathogenic microorganisms waters can have negative impact human animal health, as well marine...
Novel protocol for integration of object inside stereolithography-based chips and proof-of-concepts: bacteria imaging, blue energy in-flow cell capture.
Cancer is a leading cause of death worldwide and actual analytical techniques are restrictive in detecting it. Thus, there still challenge, as well need, for the development quantitative non-invasive tools diagnosis cancers follow-up care patients. We introduce first overall interest electronic nose or tongue such application microsensors arrays with data processing complex media, either gas (e.g., Volatile Organic Compounds VOCs biomarkers breath) liquid modified nucleosides urinary...
In this work, two-photon polymerization three-dimensional laser writing is used to integrate a microlens on the surface of single mode polarization-stable vertical-cavity surface-emitting (VCSEL) be as current-driven tunable source in compact optical guided-wave gas sensor. The conditions are optimized enable on-demand room temperature and single-step fabrication at post-mounting stage. We show that time 5 min sufficient fabricate efficiently reduces VCSEL beam divergence, without...
Turbidity is a commonly used indicator of water quality in continental and marine waters mostly caused by suspended colloidal particles such as organic inorganic particles. Many methods are available for the measurement turbidity, ranging from Secchi disk to infrared light-based benchtop or situ turbidimeters well acoustic methods. The operational methodologies large majority turbidity instruments involve physics light scattering absorption when passed through sample. As such, case...
This paper presents an experimental platform allowing in situ measurement aqueous medium using acoustic Love wave sensor. The aim of this platform, which includes the sensor, a test cell for electrical connections, microfluidic chip, and readout electronic circuit, is to realize first estimation water quality without transportation samples from field laboratory as medium-term objective. In step, validate ability such operate Amazonian water, isolated difficult-to-access location, namely,...

The flows at the intake and exhaust of an internal-combustion engine are most time simplified to a single space dimension, hyperbolic partial differential equations that govern compressible unsteady air flow discretized solved numerically. This method is basis today’s simulation codes. Models for complex parts such as charge coolers often need calibration with experimental data essentially pressure drop coefficients corrected lengths. Another technique understanding wave action inside pipes...
This study presents two experiments addressing the representation of scientific data, in particular airflows, with a user-centered design approach.
