Abstract: Various embodiments of the present disclosure disclose methods and systems for heat exchange in an opto-fluidic instrument. The opto-fluidic instrument includes a sample interface module (SIM), an illumination module, a camera module, and a reagent deck. A coolant from a coolant reservoir is directed into one or more of the modules so that heat exchange occurs at each module with the coolant. The heated coolant from the one or more modules flows to a radiator for cooling, for example, with fans flowing ambient air over the radiator, before the cooled coolant is returned to the coolant reservoir for subsequent use in cooling the modules.

Abstract: Various embodiments of the present disclosure disclose methods and systems for dispensing a reagent into a sample well and efficiently extracting the dispensed reagent from the sample well after the reagent is used for detecting molecules in a sample. The amount of probe reagents dispensed may be no more than what is needed to immerse the sample and allow effective probing of the sample by the probes in the reagent.

Abstract: A bottle connection assembly is configured to seal a bottle and provide a fluidic path between the interior of the bottle and its exterior for drawing fluids therefrom. The fluids can be reagents used for preparing a sample for the identification of target molecules. A bottle cap for capping the bottle is positioned below the bottle interface assembly and includes a female fitting configured to engage with a male fitting of the bottle interface assembly to form a sealed fluidic connection.

Abstract: Systems that include blister packs and methods of use thereof are disclosed. In various embodiments, a system includes a blister pack having at least one blister comprising a base and a top layer. The blister contains a liquid reagent. The system further includes an actuator configured to release the liquid reagent from the blister. The system further includes a substrate configured to hold a tissue sample and receive the liquid reagent from the blister upon release.

Abstract: The present disclosure provides compositions and methods for making and using a support (e.g., a sample slide) for sample analysis. The present disclosure also provides compositions, methods, and systems for processing a sample on the support for use in nucleic acid sequence detection.
