The present technology provides for a fluorescent detector that is configured to detect light emitted for a probe characteristic of a polynucleotide. The polynucleotide is undergoing amplification in a microfluidic channel with which the detector is in optical communication. The detector is configured to detect minute quantities of polynucleotide, such as would be contained in a microfluidic volume. The detector can also be multiplexed to permit multiple concurrent measurements on multiple polynucleotides concurrently.

A microfluidic, chip-based assay device has been developed for measuring physical properties of an analyte (particularly, whole blood or whole blood derivatives). The technologies can be applied to measure clotting times of whole blood or blood derivatives, determine the effects of anticoagulant drugs on the kinetics of clotting/coagulation, as well as evaluate the effect of anticoagulant reversal agents. These technologies can additionally be used to optimize the dosage of anticoagulation drugs and/or their reversal agents. The assay is independent of the presence of anticoagulant; clotting is activated by exposure of the blood sample in the device to a glass (or other negatively charged material such as oxidized silicon) surface, which activates the intrinsic pathway and can be further hastened by the application of shear flow across the activating materials surface. The absence of chemical activating agents and highly controlled and reproducible micro-environment yields a point of care universal clotting assay.
