Apparatus and methods for performing microfluidic-based biochemical assays

An apparatus for performing microfluidic-based biochemical assays, the apparatus comprises:

• a microfluidic device, wherein the microfluidic device comprises:
• at least a microfluidic feature comprising at least a reservoir configured to contain at least a fluid;
• and
• at least an alignment feature for positioning and attaching a sensor device, wherein the at least an alignment feature is not contacting the at least a microfluidic feature;
• at least a sensor device, wherein the at least a sensor device is configured to:
• be in sensed communication with the at least a fluid;
• and
• detect at least a sensed property;
• and
• at least a flow component fluidically connected to the at least a microfluidic feature, the at least a flow component configured to flow the at least a fluid through the at least a sensor device.
