Abstract
A biological sample analysis system including a sample preparation system forming droplets of segmented sample separated by a carrier fluid immiscible with the sample. The droplets include reaction mixtures for amplification of at least one target nucleic acid. A thermal cycling device having a sample block having a plurality of controlled thermal zones, and a containment structure in thermal communication with the plurality of controlled thermal zones. The containment structure receives and contains the droplets of segmented sample separated by the immiscible carrier fluid from the sample preparation system. A controller for controlling a temperature in each thermal zone of the sample block. A detection system detects electromagnetic radiation emitted from each of the droplets individually from the queue of droplets as they flow past the detection system. A positioning system to facilitate moving a queue of the droplets in the thermal cycling device relative to the detection system.
