Abstract: A microfluidic cartridge for detecting one nucleic acid of a sample, including a plurality of functional volumes split into functional areas and a fluidic network of microchannels. At least three functional areas are fluidly connected to a central distribution hub of fluids by one or more hub-connected microchannels, the central distribution hub being capable of pumping and injecting fluids from a first functional area to a second functional area by passing through the central distribution hub; and at least three valves of hub-connected microchannels are arranged so that the at least three valves are adapted to be actuated mechanically by a single external cam-driven actuator.

Abstract: A biochip device comprising a substrate constituted by at least one plate of material forming a multimode planar waveguide and carrying chromophore elements suitable for emitting fluorescence in response to excitation by guided waves having an evanescent portion, the device being characterized in that it includes coupling means for coupling excitation light with the waveguide in the form of guided waves, the coupling means being substantially non-directional.
