Oxygen Measurement Core

O2M’s “Oxygen Measurement Core” is a collaborative research facility. We collaborate with members from academia, industry, and government to perform preclinical research that involves in vitro and small animal in vivo oxygen imaging experiments. Our specific expertise is in Cancer, Type I Diabetes, Biomaterials, Tissue Grafts, Neurodegenerative Diseases, and expanding to other areas.

All experiments are performed using O2M’s preclinical oxygen imager, JIVA-25™, that can accommodate sample size up to 40 mm.
