METHOD AND DEVICE FOR MANIPULATING AND OBSERVING LIQUID DROPLETS

摘要

The invention relates to a device and a method for manipulating and observing particles suspended in a liquid. The device comprises: a first substrate (12) having at least a first orifice (21) forming a site for the entry of said liquid; an observation site (100), for observing the suspended particles; and means for displacing the liquid from said entry site (21) to said observation site (100). According to the invention, since the first substrate (12) includes a first hydrophobic layer (52) and the liquid is electrically conducting, said means for displacing the liquid are capable of displacing said liquid in the form of a droplet (F1) by electrowetting, said droplet (F1) being in contact with said hydrophobic layer (52).
