Intracellular bioactive molecules are essential for the maintenance of homeostasis in living organisms. Abnormal levels them closely related to occurrence and development some diseases. Hence, direct accurate visualization these is vital importance exploring their pathological roles. However, low-content, short-lived, widely distributed properties impede comprehensive analysis dramatically. Fluorescence photoacoustic dual-mode imaging technology provides a new solution above issue. Specifically, combination fluorescence photoacoustic, which possesses advantages high resolution in-depth tissue analysis, enables more systematic exploration pathogenic mechanisms molecules. Moreover, due structural tailorability small molecule probes, numerous probes have been developed meet demand real-time tracking cells or vivo. this review, we briefly summarize key advances dual-modal within recent years (2015-2021). A particular focus placed on design strategies biological applications detection various Furthermore, challenges further prospects hot field highlighted.

Owing to having a unique mechanism kill cancer cells via the membrane accumulation of lipid peroxide (LPO) and downregulation glutathione peroxidase-4 (GPX-4), ferroptosis therapy (FT) tumors based on Fenton reaction iron nanoparticles has been receiving much attention in past decade; however, there are some hurdles including uncontrollable release ions, slower kinetics intracellular reaction, poor efficacy FT that need be overcome. Considering cooperative coordination multivalent thiol-pendant polypeptide ligand with we put forward facile strategy for constructing iron-coordinated nanohybrid methacryloyloxyethyl phosphorylcholine-grafted polycysteine/iron ions/tannic acid (i.e., PCFT), which could deliver higher concentration ions into cells. The dynamic unsaturated PCFT is favorable stimuli-triggered fast realize efficient FT, while its intrinsic photothermia would boost induce synergistic effect between photothermal (PTT). Both immunofluorescence analyses reactive oxygen species (ROS) LPO confirmed resulted during process greatly boosted ferroptosis, Western blot assay corroborated expression level GPX-4 was downregulated by highly degraded PTT-FT vitro. Excitingly, single intravenous dose plus one NIR irradiation, vivo treatment completely eradicated 4T1 without skin scar tumor recurrence 16 days, demonstrating prominent antitumor efficacy, as evidenced GPX-4, H&E, TUNEL assays.

Carboxylesterase (CE) is crucial in metabolizing ester-containing biomolecules and particularly significant liver metabolic diseases. Herein, we present the first activatable NIRF/PA dual-mode imaging probe QHD-CE for detection of CE vitro vivo. displays excellent sensitivity selectivity with a high reaction efficiency (∼90 min). By utilizing QHD-CE, dynamic changes drug-induced injury diabetic mice models were monitored.

Lysosomes are one of the important organelles within cells, and their dynamic movement processes associated with many biological events. Therefore, real-time monitoring lysosomal dynamics has far-reaching implications. A lysosome-targeted fluorescent probe N(CH2)3-BD-PZ is proposed for kinetic motility. Using this probe, process lysosomes under starvation induction was successfully explored through fluorescence imaging. Importantly, we observed a new pattern movement, in which an irregular lysosome slowly cleaved into two different-sized touching then fused to form round lysosome. This research provides powerful tool understand motility intracellular
