Abstract
AbstractFluorescence imaging utilizing traditional organic fluorophores is extensively applied in both cellular and in vivo studies. However, it faces significant obstacles, such as low signal‐to‐background ratio (SBR) and spurious positive/negative signals, primarily due to the facile diffusion of these fluorophores. To cope with this challenge, orderly self‐assembled functionalized organic fluorophores have gained significant attention in the past decades. These fluorophores can create nanoaggregates via a well‐ordered self‐assembly process, thus prolonging their residency time within cells and in vivo settings. The development of self‐assembled‐based fluorophores is an emerging field, and as such, in this review, we present a summary of the progress and challenges of self‐assembly fluorophores, focusing on their development history, self‐assembly mechanisms, and biomedical applications. We hope that the insights provided herein will assist scientists in further developing functionalized organic fluorophores for in situ imaging, sensing, and therapy.
