<p>The invention concerns a method for significantly increasing the performance of selective dispensing of micro-droplets, for producing spatial and targeted selectivity by dispensing a predetermined reagent on a predetermined site, and in providing an easily adaptable multifunctional system. One embodiment of the inventive system comprises a substrate (2) covered with a diaphragm (3) and means for deforming (65) the diaphragm perpendicular to each cavity formed in the substrate, and wherein the cavities, etched in a material forming the substrate (2) according to a matrix-type arrangement, are in the form of wells (10) passing through the substrate with axially symmetrical continuous side walls (11); each well emerges onto an upper surface and a lower surface of the substrate respectively as a feeding orifice (12) and a discharge orifice (14), the feeding orifice having an opening substantially greater than the nozzle orifice (13).</p> |
