Mem-RhoNox is a fluorescent probe used to detect labile Fe (II) on the plasma membrane surface and inside endosomes during iron uptake in live cells. Mem-RhoNox can anchor to the extracellular surface of the plasma membrane; upon contact with Fe (II), its N-oxide group undergoes a deoxygenation reaction, converting weakly fluorescent Mem-RhoNox into strongly fluorescent Mem-Rhodamine. During transferrin-mediated endocytosis, Mem-RhoNox enters endosomes together with the transferrin-transferrin receptor complex, and reacts with Fe (II) released by transferrin to enable detection of endosomal Fe (II) .

Golgi-hNR is a cell membrane-permeable Golgi-targeted fluorescent probe containing a sulfonamide group. Golgi-hNR selectively accumulates in the Golgi apparatus of living cells, enabling real-time tracking and homeostasis assessment of reversible pH changes in the Golgi apparatus. Golgi-hNR exhibits a pH-dependent "off-on" fluorescence response mechanism within the pH 7.4-3.0 range, and its red fluorescence intensity decreases with increasing pH. The Ex/Em of Golgi-hNR is 560/664 nm and 580/664 nm, with the maximum emission peak located at 615 nm .

Endo-pH is a cell-permeable, pH-responsive fluorescent probe based on BODIPY, with a pKa of 5.08. When pH decreases from 7.32 to 4.97, Endo-pH undergoes protonation under acidic conditions, resulting in a 79-fold increase in fluorescence intensity at 786 nm. The detection wavelengths of its protonated form are Ex/Em=688/786 nm, while the absorption wavelength of its non-protonated form is 745 nm. Endo-pH can be used for staining late endosomes in live cells and determining the fusion time of late endosomes and lysosomes .

BF-170 is a selective tau fibril binding agent with an EC50 of 221 nM. It exhibits good blood-brain barrier permeability, and after intravenous injection in mice, the concentration in brain tissue reaches 9.1% ID/g within 2 minutes (with a brain clearance rate of 0.25% ID/g after 30 minutes). BF-170 can be used as a probe for tau protein pathology imaging in Alzheimer's disease (AD). It plays an important role in early-stage AD research and holds potential for imaging studies of tau-related neurodegenerative diseases .

DCA is a Fluorescent probe for visualization of phase behavior in ER membranes. DCA is an ER-targeting, polarity-responsive NIR ratiometric probe, with its p-toluenesulfonamide group responsible for ER localization; its sensitivity to polarity relies on its donor-π-acceptor (D-π-A) structure, where aniline acts as the donor and dicyanomethylene acts as the acceptor, driving an intramolecular charge transfer (ICT) process upon excitation. In environments with low polarity, such as the closely packed, low water content ERₒ phase of ER membranes, DCA emits at a shorter wavelength, while in high polarity environments like the loosely packed, higher water content ERd phase, ICT leads to a red-shifted emission, allowing discrimination of the two phases via dual NIR emission colors and ratiometric imaging. Ex/Em = 488/570–620 nm and 488/665–735 nm; additional excitation/emission pairs include Ex/Em = 488/631 nm in low polarity 1,4-dioxane and Ex/Em = 488/677 nm in 1,4-dioxane with 30% water, the higher polarity condition. It shows a large Stokes shift of ~170 nm, and pH, viscosity, and biologically relevant species including Cys, GSH, H₂O₂, and metal ions do not exert marked interference on its fluorescence spectra[1].
