Abstract
A micro-structured substrate to support a liquid sample having a lower face and an upper face. At least one surface cavity of volume V0 opening onto the upper face and forming a zone for analyzing the liquid sample. A first groove having a first volume V1, positioned around each surface cavity and opening onto the upper face thereof. The substrate also includes at least one second groove opening onto the upper face thereof and positioned around the first groove. The sum of the volumes of the second grooves is equal to V2. The volume V1+V2 is greater than or equal to 0.05 V0, preferably 0.1 V0. An analysis assembly including the substrate and the use thereof is also contemplated herein.
