Abstract
Organs-on-a-chip (OOC) are an emergent technology that bridge the gap between current invitro and invivo models used to inform drug discovery and investigate disease pathophysiology. These systems offer improved bio-relevance and controlled complexity through the integration of physical and/or chemical stimuli matched to physiologically relevant conditions. Although significant advancements have been made toward recreating organ-specific physiology on chip, the methods available to study structure and function of the cell microenvironment are still limited. Established analysis approaches, including fluorescence microscopy, rely on laborious offline workflows that yield limited time-point data. As the OOC field continues to evolve, there is a unique opportunity to engineer improved characterization methods into organ-chip devices. This review provides an overview of current integrated sensing approaches that address current limitations and enable real-time readout of relevant physiological parameters in OOC.
