WORKING DEVICE COMPRISING A LOCALIZED ZONE FOR CAPTURING A LIQUID OF INTEREST

摘要

The invention concerns a working device characterized in that it comprises an active surface (Sa) substantially non wetting with respect to a liquid of interest; at least one localized capture zone (Zc) of a drop of said liquid, formed on said active surface; at least one working zone (Zt) arranged with a capture zone such that the working zone is covered at least partly by a drop of the liquid when the latter is captured by said capture zone; and means for allowing a drop of said liquid to remain on said capture zone. Said device enables in particular high density matrices of drops of said liquid to be formed on a surface, in particular for performing chemical or biochemical reactions and/or for analyzing the liquid of interest at each drop. The invention is applicable in biological chips.
