Chemiluminescence, a phenomenon emitting light from chemical reactions rather than photon absorption, has gained significant interest for applications in bioimaging and biosensing due to its high sensitivity and low background interference. Now there is a growing interest in near-infrared (NIR) chemiluminescent probes for improved tissue penetration and reduced autofluorescence. This review summarizes NIR emissive chemiluminescent probes based on 1,2-dioxetane and discusses their chemical structures and applications. Structure modification strategies for red-shifting wavelength and enhancing brightness include incorporating electron-withdrawing groups, designing chemiluminophore-fluorophore cassettes, and exploring alternative chemiluminescent scaffolds. This review aims to inspire the exploration of NIR chemiluminescent probes in disease detection and treatment.

Dear Editor,This letter proposes a parameter-free multiple kernel clustering(MKC)method by using shifted Laplacian *** MKC can effectively cluster nonlinear data,but it faces two main challenges:1)As an unsupervised method,it is up against parameter problems which makes the parameters intractable to tune and is unfeasible in real-life applications;2)Only considers the clustering information,but ignores the interference of noise within Laplacian.
