The broader impact/commercial potential of this I-Corps project is the development of a high-resolution reflectance imaging platform that can measure the oxygen levels in tissues. The proposed platform that may be integrated into other imaging platforms. The imaging platforms that are currently available in the market provide information about tissue oxygenation and metabolism from the same field of view. These two metrics may provide critical information about the state of tissue, which may aid in the treatment and management of diseases such as cancer, ischemia-reperfusion injury, Alzheimer’s disease, and obstructive sleep apnea. Developing better therapeutics to target these diseases demands a better understanding of tissue bioenergetics in vivo. Ultimately, successful development and commercialization of this imaging platform could provide a new look at tissue that helps improve treatment and management of disease. This I-Corps project is based on the development of a high-resolution, hyper-spectral dark field reflectance imaging platform that may be integrated into other modes of imaging to provide multi-modal spatiotemporal information from the same field of view. The initial focus of this research is to integrate the platform into a two-photon microscope to provide quantitative measures of two critical tissue-level metrics - microvascular oxygenation and cellular metabolism. There is increasing evidence that measurement of only one of these metrics does not provide direct information about the other and that measuring the spatiotemporal relationship between vascular oxygenation and cellular metabolism is important for determining long-term outcomes in diseased tissue.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个I-Corps项目更广泛的影响/商业潜力是开发一个高分辨率反射成像平台，可以测量组织中的氧气水平。 所提出的平台可以集成到其他成像平台中。 目前市场上可用的成像平台从相同的视野提供关于组织氧合和代谢的信息。这两个度量可以提供关于组织状态的关键信息，这可以帮助治疗和管理诸如癌症、缺血再灌注损伤、阿尔茨海默病和阻塞性睡眠呼吸暂停的疾病。开发针对这些疾病的更好的治疗方法需要更好地了解体内组织生物能量学。最终，这种成像平台的成功开发和商业化可以提供一种新的组织视角，有助于改善疾病的治疗和管理。该I-Corps项目的基础是开发一个高分辨率、超光谱暗场反射成像平台，该平台可集成到其他成像模式中，从同一视场提供多模态时空信息。 这项研究的最初重点是将该平台集成到双光子显微镜中，以提供两个关键组织水平指标的定量测量-微血管氧合和细胞代谢。有越来越多的证据表明，测量这些指标中的一个并不能提供关于另一个的直接信息，并且测量血管氧合和细胞代谢之间的时空关系对于确定病变组织的长期结果非常重要。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。
