DXB-NIR is a push-pull dioxaboron fluorescent probe with solvatochromic properties, featuring high fluorescence brightness, photostability, and a large two-photon absorption cross-section. DXB-NIR exhibits Ex/Em of 550/620–780 nm (with two-photon excitation at 930 nm). DXB-NIR quantifies local polarity via the intensity ratio I (>640)/I (<640) between the far-red channel (<640 nm) and the near-infrared channel (>640 nm), and it can simultaneously label the plasma membrane, endoplasmic reticulum, and lipid droplets in live cells. DXB-NIR monitors the increase in local polarity of various cell compartments under conditions of cholesterol depletion, starvation, and oxidative stress. DXB-NIR can be used for polarity imaging of biological membranes and lipid droplets, as well as studies related to cellular stress .

SSR-LDs is a fluorescent probe for lipid droplet polarity detection and lipid droplet imaging. SSR-LDs exhibits polarity-dependent fluorescence: it produces intense short-wavelength emission in low-polarity environments, while generating weak long-wavelength emission in high-polarity environments. SSR-LDs enters cells via free diffusion, specifically targets lipid droplets, and is unaffected by intracellular viscosity or pH values ranging from 4.5 to 9.0. SSR-LDs shows variable Ex/Em wavelengths in different solvents, including 590/663 nm in THF, 600/660 nm in mouse tissue and in vivo imaging, and an excitation wavelength of 580 nm with an emission wavelength range of 610-750 nm in cell imaging. SSR-LDs can be used for research related to fatty liver, liver injury and hepatitis .

Mito-polarity is a mitochondria-targeted polarity probe. Mito-polarity can be used to detect mitochondrial polarity. The detection mechanism of Mito-polarity is based on an intramolecular charge transfer (ICT) system designed with a donor-π-bridge-acceptor (D-π-A) structure. Among them, the 467 nm green emission generated by the Coumarin (HY-N0709) structure is extremely sensitive to polarity changes, while the 642 nm red emission produced by the extended π-conjugation and ICT effect between the Coumarin and benzothiazine structures shows only a weak response, thus forming a ratiometric fluorescence response that is linearly correlated with solvent polarity. When Mito-polarity is excited at 405 nm in methanol, its excitation/emission wavelengths are Ex/Em = 405/467 nm and Ex/Em = 405/642 nm, with maximum absorption wavelengths of 426 nm and 561 nm .

LJ-2P is an NIR-II small-molecule fluorescent probe with fibrin/fibrinogen affinity. LJ-2P can bind coagulation-related proteins and restrict dye molecular motion, thereby enhancing local fluorescence for high-contrast imaging of bleeding and blood clots in vivo. LJ-2P can also co-precipitate with Ca 2+ to form LJ-2P nanoparticles, significantly enhancing NIR-II luminescence through the precipitation-enhanced emission (PEE) mechanism. LJ-2P can be used for research on bleeding disorders and breast cancer. LJ-2P exhibits dual-modal emission properties (Ex/Em ≈740/945 nm or 740/1066 nm) .

AF555 Picolyl Azide is a Fluorescent dye that enables site-specific fluorescent labeling via click chemistry. AF555 Picolyl Azide conjugates with the non-canonical amino acid N-propargyl-L-lysine introduced through ochre stop codon suppression via the copper (I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, achieving labeling of hyperpolarization-activated cyclic nucleotide-gated HCN channels; its picolyl group accelerates the CuAAC reaction rate, thus completing labeling rapidly at room temperature and minimizing copper-induced cytotoxicity. AF555 Picolyl Azide forms covalent bonds with the alkynyl groups of nucleotide analogs through its azide moiety, labeling viral genomes containing 5-ethynyl-2'-deoxyuridine for visualization via fluorescence microscopy .

Callose Staining Solution (Aniline Blue, Bright-Field Method) is a fluorescent dye used for detecting callose in plant tissues, green algal cell walls, plant cells, and protoplasts. Callose Staining Solution (Aniline Blue, Bright-Field Method) specifically binds to callose, a β-(1,3)-D-glucan polymer, and exhibits blue-green fluorescence under alkaline conditions with reduced background staining and non-toxicity to living cells. Callose Staining Solution (Aniline Blue, Bright-Field Method) is suitable for observation under UV or epifluorescence microscopy (Ex/Em = 365-370/397-509 nm). Callose Staining Solution (Aniline Blue, Bright-Field Method) can be used in studies related to the visualization of callose deposition in plants .

tBu2bpy is a bidentate nitrogen ligand that coordinates with Pt (II) and Pt (IV) to form functional complexes. The tBu2bpy Pt (II) bis-crown ether complex selectively recognizes Mg 2+ and Zn 2+; both ions significantly enhance the fluorescence of the complex and cause a blue shift of the absorption peak. Its six-coordinate Pt (IV) complex [Pt (X)2Me2 ( tBu2bpy)] inhibits the proliferation of tumor cells. tBu2bpy Pt (IV) complexes bind to DNA through multiple interactions including partial intercalation, groove binding, and electrostatic interaction, and can competitively displace ethidium bromide and covalently bind to purine nucleotides. tBu2bpy can be used in relevant research in fields such as organic synthesis .

DiOC5(3) (3,3′-Dipentyloxacarbocyanine iodide) is a mitochondrial Fluorescent dye that alters membrane potential, and it also acts as an inhibitor of NADH-ubiquinone reductase (respiratory complex I). DiOC5(3) increases the NADH/NAD ratio and induces excessive production of ROS. DiOC5(3) induces Apoptosis. DiOC5(3) accumulates in the mitochondria of leukemia stem-like cells via organic anion-transporting polypeptides, specifically labels these cells, and inhibits their proliferation. DiOC5(3) enhances the cellular uptake of Hoechst 33342 (HY-15559), reduces Hoechst 33342-associated cytotoxicity, and improves the resolution of DNA content analysis by flow cytometry. DiOC5(3) shows no detectable fluorescence signal when excited in the 400-500 nm ultraviolet light range. DiOC5(3) is applicable to leukemia-related research .
