EVAPORATION MANAGEMENT IN DIGITAL MICROFLUIDIC DEVICES
Described herein are digital microfluidic (DMF) devices and corresponding methods for managing reagent solution evaporation during a reaction. Reactions on the DMF devices described here are performed in an air or gas matrix. The DMF devices include a means for performing reactions at different temperatures. To address the issue of evaporation of the reaction droplet especially when the reaction is performed at higher temperatures, a means for introducing a replenishing droplet has been incorporated into the DMF device. A replenishing droplet is introduced every time when it has been determined that the reaction droplet has fallen below a threshold volume. Detection and monitoring of the reaction droplet may be through visual, optical, fluorescence, colorimetric, and/or electrical means.
Temperature control system
Provided is a temperature control system applied to an apparatus for analyzing a sample using a pipette nozzle and a reaction container, including a pipette tip temperature controller that heats a pipette tip which is fitted on the pipette nozzle and aspirates or discharges liquid and a reaction container temperature controller that heats the reaction container. The pipette tip temperature controller heats, in a concentrated manner, at least a distal end portion of the pipette tip of the pipette nozzle located at a predetermined heating position with hot air emitted from a heat source and is configured such that a distal end is capable of arriving at the reaction container by lowering the pipette nozzle from the heating position.
Biological Analysis Systems and Methods
A biological analysis system for performing a performing an assay or experiment includes one or more of a carrier, base, or tray. The carrier, base, or tray is/are configured to interchangeably receive (1) a first block and a corresponding first cover placed over the first block or (2) a second block and a corresponding second cover placed over the second block; The system also includes a computer readable memory comprising instructions for detecting when the second cover is placed over the first block and/or for detecting when the first cover is placed over the second block based on lack of electrical continuity along an electrical path comprising one of the blocks and one of the covers.
