| 摘要 |
The present invention relates to a microstructured substrate for supporting a liquid sample comprising a lower face and an upper face which comprises, on the one hand, at least one surface cavity of volume V0 opening onto said upper face and forming a zone for analysing the liquid sample and, on the other hand, a first groove having a first volume V1, positioned around each surface cavity and opening onto the upper face thereof. According to the invention, this substrate is characterized in that it also comprises at least one second groove (14, 15, 16) opening onto the upper face thereof and positioned around the first groove (13), the sum of the volumes of the second grooves being equal to V2, the volume V1+V2 being greater than or equal to 0.05 V0, preferably 0.1 V0. The invention also relates to an analysis assembly comprising the substrate and the use thereof. |
