The invention relates to a method of depositing a substance onto a substrate (), comprising: —providing a substrate () at a distance from a conducting spraying nozzle (), said spaying nozzle () having an outlet (); —providing a liquid composition containing the substance to the spraying nozzle (); —generating electrically charged liquid droplets from the liquid composition between the outlet () of the spraying nozzle () and the substrate (), by providing compressed gas around the liquid composition flowing out of the outlet () of the spraying nozzle () and by providing an electric field downstream of the outlet () of the spraying nozzle (); and—collecting the generated liquid droplets on the substrate (). The invention also relates to an installation for carrying out this method.

Method of depositing a substance on a substrate

The invention relates to a method for quantifying the level of agglutination of particles in a sample, in particular a biological sample, and notably blood. The biological sample is positioned between a light source and a matrix photodetector. The image acquired by the photodetector is representative of the level of agglutination of the particles in the sample. The light source emits a light wave, the spectral band of which extends an optimum 400 and 600 nm, which constitutes an optimum an excessively low absorption and excessively high absorption, given the thickness of the sample.

Method for determining the level of agglutination of particles in a sample

The invention is a method for characterizing a liquid sample, said liquid sample containing particles, the method comprising the following steps: The method comprises, prior to step c), applying an acoustic wave to the sample, said acoustic wave forming pressure nodes and pressure antinodes in the sample, so as to separate, in the latter, a poor portion, poor in particles, and rich portion, rich in particles, such that, in step c), the sample is characterized:
