L'objet principal de l'invention est un dispositif (1) de prélèvement d'un échantillon de liquide (L) par capillarité, comportant un canal (2) d'écoulement du liquide délimité par deux parois internes (3, 4) du dispositif (1) entre lesquelles s'étend un fond (5) de canal, la distance (D) séparant les deux parois internes (3, 4) diminuant en direction du fond (5) de canal, le canal (2) s' étendant entre une première extrémité (6) de collecte, ouverte sur l'extérieur (E) du dispositif (1) et apte à recevoir le liquide (L), et une deuxième extrémité (7), de façon à permettre l'écoulement du liquide (L) par capillarité le long du fond (5) de canal depuis la première extrémité (6) vers la deuxième extrémité (7), le canal (2) comportant, au niveau de la deuxième extrémité (7), un moyen de blocage (9, 17) apte à bloquer l'écoulement de liquide (L) dans le canal (2) depuis la première extrémité (6) vers la deuxième extrémité (7).
摘要:
Provided herein is a system, including a platform for performing at least one assay protocol. The platform may include a flow cell that can include at least one sensor. The platform may also include a reader that can be in communication with the sensor. Moreover, the sensor may maintain communication with the reader for the entirety of the performance of the assay protocols to transmit data regarding physical events within the flow cell or an electrochemical state of any substance contained within the flow cell.
摘要:
A microfluidic device includes a platform with a microstructure. The microstructure include a primary channel and a plurality of chambers that open to the primary channel to enable a sample fluid that is loaded into the device via the primary channel to flow into the chambers. Each chamber has a volume that is less than tens of nanoliters and is connected by a vent to a secondary channel of the microstructure. A width of the vent is configured to enable a gas to escape from the chamber to the secondary channel while inhibiting flow of the sample fluid from the chamber into the secondary channel.
