Abstract

Embodiments of the present disclosure relate to a microscopy system and a method to analyze fluids in flow. The microscopy system comprises a microfluidic cartridge to receive input comprising at least one of fluids and reagents. The microfluidic cartridge further comprises a mixing zone to receive the at least one of fluids and reagents to form a mixture and an imaging zone to receive the mixture from the mixing zone. An illumination unit is configured in the microscopy system to illuminate the imaging zone and at least one imaging unit to capture plurality of images of one or more microscopic elements of the mixture flowing through the imaging zone. The plurality of images is processed by a computing unit associated with the microscopy system for analyzing fluids.
