Abstract

To image live cells for prolonged periods of time, an Arduino-based, low-cost imaging incubator was constructed. The imaging incubator keeps cells viable by controlling for temperature and ${{\rm CO}_2}$ to maintain physiological conditions for cells during imaging. All devices and parts employed in the build were typical maker-type components to minimize the cost of the imaging incubator. The imaging incubator allows for real-time imaging of live cells exposed to any desired perturbation or stimulus. As a proof of the system’s functionality, cells were imaged over 24 h while remaining viable in the imaging incubator.
