Abstract: A method for collecting and analysing airborne particles, including a step of eluting particles precipitated on a collecting surface, a step of analysing the airborne particles collected in the reaction chamber, the eluting step being carried out by heating a first reservoir containing the elution liquid to a first temperature value, the analysing step being carried out by heating the reaction chamber to a second temperature value higher than the first temperature value, so as to: activate a detection reaction in the reaction chamber, isolate the reaction chamber during the detection reaction, initiate a device for sealing the reaction chamber, a step of sealing the reaction chamber.

Abstract: A fluidic component intended to be associated with a heating module and wherein there is created a fluidic circuit which includes an inlet channel and an outlet channel, the fluidic component including a fluidic valve mechanism including: a fluidtight reservoir intended to be filled with a volume of gas capable of expanding, a deformable membrane closing the reservoir in a fluidtight manner, the membrane being able to deform by expansion of the volume of gas, between a first position wherein it forms a passage between the inlet channel and the outlet channel so as to allow a fluid to pass, and a second position wherein it obstructs the passage.

Abstract: A membrane for collecting airborne particles, the membrane taking the form of a strip composed of a matrix formed from a mixture of a polymer and of a filler that is made of an electrical conductor, a hydrophilic layer for collecting particles, on which layer is deposited said matrix so as to form at least one composite layer, the membrane including at least one region obtained via a surface treatment of the hydrophilic layer.

Abstract: The invention relates to a method for tracking the amplification of a sequence of nucleotides in a sample (10). The sample is placed between a light source (12) and an image sensor (16). Under the effect of amplification reagents, mixed with the sample, a nucleotide sequence, called the target sequence, is replicated iteratively, amplifying the target sequence. The method includes the acquisition of an image representative of the formation of a precipitate in the sample under the effect of the amplification, on the basis of which an image of interest is formed. The application of a statistical indicator to the image of interest allows an indicator of the amplification of the target sequence to be determined.
