NRERcl is a Golgi-targeting lipid order probe. NRERcl can be used for imaging the lipid order and polarity of the endoplasmic reticulum. NRERcl carries a propyl chloride targeting group that directs it to the endoplasmic reticulum, and it functions via excited-state charge transfer, emitting colors according to local polarity changes associated with lipid order. NRERcl partitions into lipid membranes, with a higher fluorescence quantum yield in membrane environments than in aqueous buffers; its excitation wavelength is 520 nm, and the emission maximum varies with the environment (Ex/Em = 520/584-653 nm) .

BODi-1 is a fluorescent modulator targeting dsDNA, which binds to dsDNA via a bis-intercalation mechanism (Ex=465 nm, Em=490 nm). BODi-1 exhibits a fluorescence enhancement effect upon binding to nucleic acids, but its fluorescence intensity, anisotropy and average lifetime decrease at higher dye/DNA ratios. When BODi-1 binds to DNA in liposome complexes, it also shows red-shifted emission spectra, along with reduced quantum yield and average lifetime. BODi-1 does not induce significant DNA conformational changes when the dye/DNA ratio is below 0.01. BODi-1 can be used as a fluorescent probe for the characterization of liposome complexes and FRET studies at this ratio .

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.

Nanoclusters are essentially ultrasmall nanomaterials, typically with diameters between 1 and 10 nm, composed of a specific number of metal atoms (approximately 10 to several hundred) and ligands. This structure places their size between that of small molecules and traditional nanoparticles, exhibiting quantum effects. When the size of the metal core approaches the Fermi wavelength of electrons, its band structure transitions from a continuous state to discrete energy levels, thus exhibiting molecular-like properties such as single-electron transitions, multiple absorption bands, and strong photoluminescence. Iron nanoclusters (FeNCs) are a class of ultrasmall fluorescent nanomaterials composed of several to tens of iron atoms. Synthesized using bovine serum albumin (BSA) as a template and protectant via a chemical reduction method, these materials possess excellent optical properties and biocompatibility. Furthermore, they can be functionalized through surface modification, leading to their wide application in fields such as bioanalysis, environmental monitoring, and disease diagnosis.

FITC (Fluorescein Isothiocyanate) (solution) , is one of the green fluorescein derivatives widely used in biology. FITC has the characteristics of high absorptivity and excellent fluorescence quantum yield. The isothiocyanate group of FITC can be combined with amino, sulfhydryl, imidazole, tyrosyl, carbonyl and other groups on the protein, so as to achieve protein labeling including antibodies and lectins. In addition to its use as a protein marker, FITC can also be used as a fluorescent protein tracer to rapidly identify pathogens by labeling antibodies, or for microsequencing of proteins and peptides (HPLC). The maximum excitation wavelength of FITC is 494 nm. Once excited, it fluoresces yellow-green at a maximum emission wavelength of 520 nm. In addition, FITC is also a hapten that can induce contact hypersensitivity (CHS) and induce an atopic dermatitis model .
