TOTO-3 is a cyanine nucleic acid intercalating fluorescent probe that binds to both RNA and DNA (Ex=642 nm, Em=660 nm). TOTO-3 cannot enter intact cells, but can penetrate cells with permeabilized plasma membranes, staining cytoplasmic RNA and nucleoli to distinguish intact cells from damaged ones. TOTO-3 is taken up by macrophages in an ultrasound-independent manner. TOTO-3 accumulates in tumor cells via ultrasound-mediated enhancement of plasma membrane permeability. TOTO-3 supports optical imaging for real-time assessment of plasma membrane integrity, nucleic acid detection, and monitoring of ultrasound-mediated intracellular delivery processes. TOTO-3 is applicable to studies related to rectal cancer .

BV-1 is a fluorescent probe for viscosity detection and imaging in living cells. BV-1 can be used to detect changes in intracellular viscosity and mitochondrial viscosity in living cells. BV-1 responds to environmental viscosity via a molecular rotor mechanism. In a low-viscosity environment, the centrally located unsaturated structure induces a twisted intramolecular charge transfer (TICT) state and promotes non-radiative transitions, resulting in fluorescence quenching; when viscosity increases, molecular rotation is restricted, the TICT state is attenuated, and fluorescence is enhanced with a red shift. BV-1 can be used for real-time monitoring of changes in cytoplasmic viscosity and the viscosity increase during cell apoptosis. Ex/Em = 480/570 nm .

APC-Cy7 is an APC-tandem fluorochrome (allophycocyanin-cyanine 7) and degradable fluorochrome, with maximum absorption at ~650 nm, peak emission at 767 nm when excited by a 633 nm red laser, and cell-dependent degradation. APC-Cy7 undergoes time-dependent degradation (decoupling) when bound to peripheral blood leukocytes, leading to nonspecific APC channel signal, with degradation cell type-dependent. APC-Cy7 shows reduced degradation when immunolabeled cells have inhibited metabolic activity or are incubated with vitamin C. APC-Cy7 serves as a tandem fluorochrome in multiparametric flow cytometry for detection of leukocyte surface proteins when conjugated to specific antibodies (Ex/Em = 650 nm/778 nm) .

CL-NC is a chemiluminescent probe used for in vivo imaging of N-methyl-D-aspartate receptors (NMDARs), and its detection mechanism relies on bioorthogonal activation achieved via a tetrazine-triggered click-to-release reaction. The isonitrile group of CL-NC undergoes a click reaction with tetrazine, followed by hydrolysis and β-elimination to release a phenoxide anion, which induces the departure of adamantane and generates chemiluminescence. CL-NC has a maximum absorption wavelength of approximately 425 nm, a maximum fluorescence emission wavelength of approximately 670 nm, and a maximum chemiluminescence emission wavelength of 710 nm. When used in combination with Tz-IFDL (HY-D3369), an NMDAR ligand conjugated with tetrazine, CL-NC enables targeted imaging of NMDARs in living cells, as well as in the brain and spinal cord of living mice .

LumiPK is an environment-sensitive probe that specifically targets the liver isoform of pyruvate kinase (PKL). LumiPK exhibits high affinity for PKL with a Kd of 37 nM. LumiPK integrates the 4-sulfonamido-7-aminobenzoxadiazole (SBD) fluorophore into a phthalazine scaffold, and its fluorescence intensity changes with the polarity of the chemical environment, thereby directly reflecting protein occupancy. LumiPK binds only to the tetrameric form of PKL, with the binding site being an allosteric pocket formed at the subunit interface, and key water-mediated interactions enhance its potency; in polar environments such as buffer, its fluorescence is significantly quenched, whereas upon binding to the nonpolar allosteric pocket of PKL, its fluorescence is enhanced. In fluorescence detection, its excitation/emission wavelengths are Ex/Em = 450/550 nm .

Biotin-16-dCTP is a biotinylated deoxycytidine triphosphate that serves as an important DNA labeling substrate. Biotin-16-dCTP can be enzymatically incorporated into the 3' end of DNA probes via terminal deoxynucleotidyl transferase, forming a 1-3 nucleotide-long tail to achieve biotinylation of the probes. Biotin-16-dCTP enhances chemiluminescent detection of low-abundance targets such as specific tRNA isoacceptors through Northern blotting. Biotin-16-dCTP can also replace conventional dCTP to be integrated into single-stranded DNA generated by asymmetric polymerase chain reaction, which is applicable for bioconjugation or pull-down assays. Repeated freeze-thaw cycles of Biotin-16-dCTP should be avoided to prevent degradation of its function for probe biotinylation .

Metal nanoclusters, containing anywhere from a few to hundreds of atoms, bridge the gap between nanoparticles and molecular compounds, typically exhibiting molecular-like electrical and optical properties. Furthermore, metal nanoclusters possess advantages such as significant Stokes scattering and size- and ligand-dependent fluorescence characteristics, making them an emerging class of materials for constructing fluorescence platforms. Current research primarily focuses on the synthesis and application of noble metal nanoclusters like gold and silver. However, copper, belonging to the same group as gold and silver in the periodic table, is inexpensive, environmentally friendly, readily available, has a simple preparation process, and low toxicity, making it widely applicable in industry. In addition, copper nanoclusters exhibit better photostability than organic dyes and better environmental friendliness than semiconductor quantum dots, making them suitable for trace detection.

ASSI-Leu is a novel AIE fluorescent probe based on an asymmetric tetraaryl imidazole skeleton, which can be used for ratiometric imaging detection of endogenous leucine aminopeptidase. ASSI-Leu contains an L-leucine-based recognition group that blocks the excited-state intramolecular proton transfer (ESIPT) in its 2-(2'-hydroxyphenyl) benzothiazole (HBT) skeleton, thereby generating an enol-form emission signal at Ex/Em = 365/417 nm. ASSI-Leu undergoes cleavage of the L-leucine group mediated by LAP to form ASSI-OH, which further activates aggregation-induced emission (AIE) and ESIPT, generating a keto-form emission signal at Ex/Em = 365/554 nm and producing a ratiometric fluorescent signal. ASSI-Leu enables real-time tracking of LAP in cancer cells and zebrafish models .\n
