The present invention provides a method for a picoliter volume microfluidic assay. The method includes the steps of providing a first solution comprising a sensor, preparing a sample comprising at least one analyte, and combining the sample with an indicator, thereby forming a second solution. The method further includes co-encapsulating the first solution and the second solution in a plurality of droplets with a microfluidic device, incubating the plurality of droplets, thereby forming at least one complex comprising the sensor, at least one analyte and indicator, and detecting the at least one complex. A primary signal associated with the at least one complex is distinguishable from a background signal associated with at least one of the sensor, at least one analyte and indicator individually. |
