| description | Methods, systems, and kits for determining dissolved oxygen levels within a microfluidic device are provided. Microfluidic devices may be suitable for cell culture. The methods, systems, and kits may also be used to determine oxygen consumption levels in a population of biological micro-objects. In particular, the methods, systems and kits of the present disclosure depend on flowing a fluid medium comprising a dye and a supplied partial pressure of oxygen into a microfluidic device for a period of time wherein fluorescence emitted by the dye varies based on the availability of oxygen near the dye; acquiring a fluorescence image of an indoor region of interest; and correlating the fluorescence of the fluorescence image of the region of interest with a reference to determine the oxygen partial pressure observed in the region of interest.
