The invention concerns a method for significantly increasing the performance of selective dispensing of micro-droplets, for producing spatial and targete d selectivity by dispensing a predetermined reagent on a predetermined site, a nd in providing an easily adaptable multifunctional system. One embodiment of t he inventive system comprises a substrate (2) covered with a diaphragm (3) and means for deforming (65) the diaphragm perpendicular to each cavity formed i n 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 wel ls (10) passing through the substrate with axially symmetrical continuous side walls (11); each well emerges onto an upper surface and a lower surface of t he 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).
