摘要:
Embodiments of the invention provide fluidic devices such as, but not limited to, microfluidic chips, with one or more freeze thaw valves (FTVs) employing one or more ice-nucleating agents (INAs), that can reliably operate to freeze at relatively higher temperatures and/or at faster rates than conventional microfluidic devices with FTV systems.
摘要:
Analysis systems with a housing having a chamber sized and configured to receive at least one microfluidic device. The systems also include an optic system coupled to the housing in optical communication with the at least one microfluidic device, a controller coupled to the optic system, a heat source coupled to the optic system and thermally coupled to the at least one microfluidic device held in the housing, and a sub-array selection module in communication with the controller. The sub-array selection module is configured to select a sub-set of sets of microwells of at least one fluid channel of the microfluidic device for imaging by the optic system after a reaction step (e.g., one thermocycle) during an assay.

摘要:
A fluidic device includes a plurality of reaction wells, typically in a dense array, with at least one bead retention segment in fluid communication with and spatially separated from at least one signal detection segment. A respective bead retention segment can be configured to hold a single bead, which can have a reagent attached thereto.
