Hypoxia in solid tumors is an important factor in radiation therapy resistance, but partial pressures of oxygen in the tissue are heterogenous and difficult to measure. Here the authors develop Cherenkov excited phosphorescence imaging using oxygen p

Introduction: Tumor hypoxia confers both a poor prognosis and increased resistance to oncologic therapies, and therefore, hypoxia modification with reliable oxygen profiling during anticancer treatment is desirable. The OxyChip is an implantable oxyg
