Abstract: 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.

Abstract translation: 微流体装置包括具有微结构的平台。 微结构包括主通道和多个腔室，其通向主通道，以使经由主通道加载到设备中的样品流体流入腔室。 每个室具有小于数十纳升的体积，并且通过排气口连接到微结构的第二通道。 排气口的宽度被配置成使得气体能够从腔室逸出到次级通道，同时抑制样品流体从腔室流入第二通道。
