Work device comprising bordered work zones, on-chip laboratory and microsystem
First Claim
1. Work device (1) comprising:
- a work box (Bo) provided with means (o, s) for introducing a liquid of interest (E) into the box and for extracting the liquid of interest from the box, a substrate (S) comprising an active surface that is substantially non-wetting for said liquid of interest contained in said box, a plurality of distinct work zones (Zt) formed on said active surface and each surrounded by a border (b) formed on said active surface that is substantially non-wetting for the liquid of interest, the borders not touching one another and having no common edge, in which the means (o, s) for introducing and extracting the liquid of interest respectively into and from the box are arranged on said work box in such a way that when the liquid of interest is introduced into the box (BO), it covers the work zones and their respective border, and in which the borders have a geometry such that when the liquid of interest is extracted from the box, after having been introduced therein, a drop (g) of the liquid of interest (E) remains imprisoned by each border (b) and in contact with the work zone (Zt) that it surrounds.

Abstract
The present invention relates to a work device (1) comprising work zones. It can be used to obtain a matrix of drops on a surface, using a liquid of interest (E). It comprises a work box (Bo) provided with means (o, s) for introducing and extracting the liquid respectively into and from the box; a substrate (S) comprising an active surface that is substantially non-wetting for said liquid of interest contained in said box; distinct work zones (Zt) formed on said active surface and each surrounded by a border (b) formed on said active surface, the borders not touching one another and having no common edge and having a geometry such that when the liquid of interest is extracted from the box, a drop (g) of the liquid of interest remains imprisoned by each border and in contact with the work zone that it surrounds.
