Stimuli-responsive linkers and their application in molecular imaging

Stimuli-responsive linkers are appealing tools to improve the specificity, sensitivity, and efficacy of molecular imaging. In this review, the recent examples and progress toward the development of stimuli-responsive linkers and their application in molecular imaging are systematically summarized, highlighting the potential of these linkers in the design of activatable molecular imaging probes.

Abstract:

Molecular imaging is a non-invasive imaging method that is widely used for visualization and detection of biological events at cellular or molecular levels. Stimuli-responsive linkers that can be selectively cleaved by specific biomarkers at desired sites to release or activate imaging agents are appealing tools to improve the specificity, sensitivity, and efficacy of molecular imaging. This review summarizes the recent advances of stimuli-responsive linkers and their application in molecular imaging, highlighting the potential of these linkers in the design of activatable molecular imaging probes. It is hoped that this review could inspire more research interests in the development of responsive linkers and associated imaging applications.
