Lysosomal biothiols play critical roles in numerous cellular processes and diseases. Researching an effective method for real-time labeling biothiols in lysosomes is of great significance and urgency, as it could provide essential information for the diagnosis of relevant diseases. In this study, we developed a lysosome-targeted fluorescent probe (LY-DCM-P) with a large Stokes shift of 150 nm for the sensitive and selective detection of biothiols and . Additionally, LY-DCM-P showed low cytotoxicity and excellent lysosome-targeted ability. The probe was successfully employed to monitor fluctuations in lysosomal biothiols in various living systems, enabling enormous potential to accurately monitor the occurrence and progress of biothiol-related diseases.

Abnormal lysosomal viscosity is closely associated with cancer progression, underscoring the need for bifunctional fluorescent probes and photosensitizers (PSs) that can both monitor viscosity and facilitate imaging-guided therapy for simultaneous cancer diagnosis and treatment. Despite advances in lysosome-targeted PSs development, few have demonstrated the ability to generate both Type I and Type II reactive oxygen species (ROS). In this study, we present BTTPA, a lysosome-targeted fluorescent probe and photosensitizer, designed to integrate cancer diagnosis via viscosity imaging and cancer treatment through photodynamic therapy (PDT).

Smartphone-assisted visual assay not only expands quantitative analysis but also enhance real-time on-site sensing capabilities. Herein, lysosome-targeted dual-emissive carbon dots (L-CDs) can not only recognize Hg and SO by ratiometric fluorescence and ratiometric absorption, but also visually quantify Hg and SO by smartphone-assisted method. With monitoring of intrinsic ratiometric fluorescent variation (I/I), L-CDs are developed as an effective sensing platform for ratiometric fluorescent successive identification of Hg and SO accompanying with continuous fluorescence variation of blue, purplish pink, pink, and light yellow.

Abnormal levels of zinc ions within endo-lysosomes have been implicated in the progression of Alzheimer's disease (AD), yet the detection of low-concentration zinc ions at the organelle level remains challenging. Here we report the design of an endo-lysosome-targeted fluorescent reporter, Znluor, for imaging endogenous zinc ions. Znluor is constructed from an amphiphilic DNA framework (DNF) with programmable size and shape, which can encapsulate zinc-responsive fluorophores within its hydrophobic nanocavity.

Developing new anticancer agents can be useful, with the ability to diagnose and treat cancer worldwide. Previously, we focused on examining the effects of nonoxidovanadium(IV) complexes on insulin mimetic and cytotoxicity activity. In this study, in addition to the cytotoxic activity, we evaluated their bioimaging properties.
