NtHzBtd is a fluorescent probe for detecting Fe 3+. NtHzBtd is applicable to the selective fluorescent detection of Fe 3+ ions and live cell imaging studies. NtHzBtd can selectively coordinate with Fe 3+ to form a 1:1 complex, triggering chelation enhanced quenching (CHEQ) and intramolecular charge transfer (ICT) processes, which result in fluorescence turn-off, thereby enabling sensitive detection of Fe 3+ and live cell fluorescence imaging. After binding to Fe 3+, NtHzBtd reduces fluorescence intensity, exhibits a rapid response property, with a limit of detection of 0.036 μM and a response time of approximately 55 s. The detection wavelengths are Ex/Em = 334/401 nm (solution system) .

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 .

Dns-LLC is a cell-permeable Cu +-selective fluorescent probe that forms a 1:1 complex with Cu +. The thiol group of Dns-LLC plays a key binding role, while the sulfonamide and amide groups jointly contribute to the stabilization of the complex. Upon binding to Cu + in aqueous buffer solutions, Dns-LLC generates a turn-on fluorescence response, which can be used for the detection of Cu + in the Golgi apparatus .

Mito-RhFe is a Fluorescent probe for mitochondrial labile Fe³⁺ monitoring via imaging and flow cytometry. This probe is a rhodamine-based construct with a spirolactam fluorescence signaling group and an N2-hydroxyethyldiethylenetriamine chelator; its delocalized positive charge enables mitochondria-targeting ability in live cells, and it exhibits fine cell membrane permeability. In its native state, it exists in the non-fluorescent spirolactam form, but upon binding to Fe³⁺, it undergoes a ring-opening conversion to the fluorescent rhodamine form, triggering a turn-on fluorescent response; this process is reversible, as the addition of the metal chelator TPEN removes Fe³⁺ and converts the probe back to its non-fluorescent spirolactam form, and re-addition of Fe³⁺ restores fluorescence. The probe shows high selectivity for Fe³⁺ over most other metal cations present in living systems, with a ~90-fold fluorescence enhancement upon binding to 20 equiv of Fe³⁺. Mito-RhFe has excitation/emission wavelengths of Ex/Em = 540/578 nm, with an ~8 nm bathochromic shift in emission upon Fe³⁺ binding, and it can also be excited at 543 nm for confocal imaging with emission detected at 570-620 nm[1].

Mito-CS1 is a fluorescent probe for imaging and reversible detection of the exchangeable mitochondrial Cu + pool in living cells. Mito-CS1 combines a Cu +-responsive fluorescent platform with a mitochondria-targeted triphenylphosphonium group, which localizes the probe to mitochondria via a proton gradient. Mito-CS1 contains a thioether-rich receptor for the selective recognition and binding of Cu +, triggering a fluorescence turn-on response by inhibiting photoinduced electron transfer. The apo-form of Mito-CS1 has excitation/emission wavelengths of 555/569 nm, while those of Mito-CS1 after binding to Cu + are 550/558 nm .

TPE-SQ5 is a ratiometric Fluorescent probe for hypochlorite (ClO -) detection with a limit of detection of 5.6 nM. TPE-SQ5 exhibits high selectivity and high sensitivity towards ClO -. TPE-SQ5 can be oxidized by ClO - to form an epoxide, which quenches its deep red fluorescence; subsequently, the epoxide decomposes into a hemicyanine and a sulfonic acid-substituted oxindole, producing blue-green fluorescence to achieve a ratiometric response. TPE-SQ5 can form nanoparticles with Pluronic F-127 via the nanoprecipitation method, and these nanoparticles possess cell permeability. TPE-SQ5 has unique Ex/Em spectra in different solvents and nanoparticle forms, with emission peaks at 643 nm (380 nm excitation, 95% H2O/THF), 631 nm (564 nm excitation, DMSO), 652 nm (536 nm excitation, THF) and 630 nm (524 nm excitation, nanoparticles); the Ex/Em settings used for cell imaging are 488/550-650 nm (red channel) and 405/450-550 nm (green channel) .

MBCB is a two-photon Fluorescent probe for dual-detection of mitochondrial SO₂ derivatives and viscosity. For SO₂ derivatives detection, the probe utilizes a Michael addition mechanism: nucleophilic addition of SO₂ derivatives to the C=C bond between the carbazole skeleton and 3-methylbenzothiazolium moiety destroys the strong intramolecular charge transfer (ICT) system between these groups, while enhancing the weak ICT system between the benzothiazole group and carbazole framework; this causes the red emission at 600 nm to decrease and the blue emission at 434 nm to increase, creating a ratiometric response based on the I₄₃₄ₙₘ/I₆₀₀ₙₘ intensity ratio. For viscosity detection, in low-viscosity environments, steric hindrance creates a twisted ICT (TICT) system with weak fluorescence, while in high-viscosity environments, intramolecular rotation is blocked, the TICT state is disrupted, and the strong ICT system is recovered, leading to a strong red emission at 567 nm with negligible change to the short-wavelength emission at 415 nm, creating a ratiometric response based on the I₅₆₇ₙₘ/I₄₁₅ₙₘ intensity ratio that has a logarithmic linear relationship with viscosity. The probe has excitation/emission wavelengths of Ex/Em = 351/434, 600 nm for SO₂ derivatives detection and Ex/Em = 351/567 nm for viscosity detection, with two-photon excitation at 740 nm for bioimaging; it also exhibits good mitochondrial targeting ability with a Pearson's colocalization coefficient of 0.93 when paired with Mito-Tracker Green. The probe shows high sensitivity and selectivity for SO₂ derivatives, has low cell cytotoxicity, and can be applied to detect exogenous/endogenous HSO₃⁻ in living cells and in vivo, as well as visualize mitochondrial viscosity changes induced by nystatin[1].
