SYSTEM AND METHOD FOR OPTICAL DETECTION INCLUDING A COMPOSITION FOR THE OPTICAL DETECTION OF PARTICLES, COMPRISING WATER, THE PARTICLES, A SURFACTANT, AND A HYDROPHILIC POLYMER

摘要

The invention relates to a system (20) for the optical detection of particles (30), including a transparent slide (26), a composition (28) provided on the transparent slide (26), a light source (22) suitable for illuminating the composition (28) and the slide (26), and a device (24) for acquiring at least one image of the composition (28) illuminated by the light source (22), the transparent slide (26) being arranged between the light source (22) and the acquisition device (24). The composition (28) includes water, the particles (30), a surfactant, and a hydrophilic polymer, wherein the particles (30) have a diameter that is preferably smaller than 10 μm, more preferably smaller than 1 μm, the concentration of the surfactant is preferably at least equal to the critical micelle concentration, and the hydrophilic polymer has a boiling point that is higher than that of water.
