System for processing biological samples using flow control and droplets
A recently granted patent (Publication Number: US11772096B2) describes a system for processing biological samples. The system includes a substrate with multiple wells for holding liquids and flow channels that are fluidically connected to the wells. A flow control system is also included, which consists of a manifold with ports that connect to the wells and containment structures for carrier fluid. The system further includes a cradle that holds the substrate in position to connect the manifold with the wells.
The flow control system is designed to transmit a pressure differential through the manifold to the wells, causing sample volumes in some of the wells to flow through the corresponding flow channels. The carrier fluid, which is immiscible with the sample volumes, also flows through the flow channels, forming droplets that contain the sample volumes separated by the carrier fluid.
Additional features of the system include a gasket to seal the interface between the manifold and the substrate, alignment means to align the wells with the manifold, and a thermal cycling system for nucleic acid amplification reactions. The system may also include a fluorescence monitoring system and a sheet of sealing material to cover the wells on the substrate's face.
The flow control system can generate a positive pressure differential using a pumping element in cooperation with the manifold. It can also transmit a pressure differential to additional wells, causing carrier fluid in those wells to flow through other flow channels. The alignment means, which may include a dowel, ensures proper alignment between the substrate's wells and the manifold when placed in the cradle.
Overall, this patented system offers a solution for processing biological samples by facilitating the controlled flow of sample volumes and carrier fluid through a substrate with wells and flow channels. It also includes various additional features to enhance functionality and efficiency, such as sealing mechanisms, alignment means, and thermal cycling capabilities.
