Abstract
AbstractDynamic changes of intracellular, extracellular, and subcellular adenosine triphosphates (ATPs) have fundamental interdependence with the physio‐pathological states of cells. Spatially selective in situ imaging of such ATP dynamics offers valuable mechanistic insights into the related biological activities. Despite significant advances in the design of aptamer sensors for ATP detection, the dearth of methods that enable precise ATP imaging in specific cellular locations remains a challenge in this field. This review focuses on the modular engineering of regulatable sensing technology via the integration of aptamer probe designs with advanced functional nanomaterials, allowing conditional control of ATP sensing and imaging with high spatial precision from subcellular organelles to living animals. Highlighting the recent advances in the design of photo‐triggered nanosensors for spatiotemporally controlled ATP imaging, endogenously‐triggered ATP sensing in a cell‐selective manner, and spatially‐controlled nanodevices for ATP imaging in specific organelles and extracellular microenvironments. Emphasis will be put on elucidating the principles of how nanotechnology can be applied to regulate the spatial precision of aptamer‐based ATP sensing activities. The authors envision that this perspective provides insights into the engineering of aptamer‐based nanobiotechnology for opening new frontiers in precise molecular sensing and other bio‐applications.
