Silver nanoclusters (AgNCs) are ultrasmall nanoparticles composed of several to tens of silver atoms. Their size is close to the Fermi wavelength of electrons, thus exhibiting unique molecular-like properties, such as strong fluorescence. Silver nanoclusters possess small size, low toxicity, excellent photostability, large Stokes shift, and good biocompatibility. Lipoic acid (also known as octylsulfonic acid) acts as a ligand in the synthesis of silver nanoclusters, primarily playing a role in stabilizing and protecting the silver nanoclusters. The ligand binds to silver atoms through its specific chemical structure, forming a stable nanocluster structure and influencing the physicochemical properties of the clusters, such as fluorescence performance, catalytic activity, and biocompatibility. This demonstrates potential application value in various fields such as chemical analysis, biosensing, catalysis, medicine, and bioimaging.

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.

PE-Cy7 is a tandem dye conjugate based on fluorescence resonance energy transfer (FRET). Composed of phycoerythrin (PE) as the donor and Cy7 as the acceptor fluorescent dye, PE-Cy7 is suitable for multicolor flow cytometry, laser scanning cytometry and immunofluorescence applications. PE-Cy7 can be conjugated to antibodies or used in the biotin-streptavidin system to label cell surface antigens in immunophenotyping and multiparametric cell analysis. PE-Cy7 undergoes photon-induced oxidative degradation, whose rate depends on light intensity and storage conditions, leading to reduced FRET efficiency and increased PE leakage. PE-Cy7 can be excited at wavelengths of 488 nm, 532 nm or ~760 nm, and its emission signal can be detected using 780/60 nm, 810/90 nm or 785/50 nm bandpass filters, with a Stokes shift of 300 nm .

Dansyl-morpholine (DNS-M) is a Fluorescent probe for lipid droplet imaging, cancer cell discrimination, and real-time tracking of lipid droplet dynamics. As a solvatochromic probe with a donor-π-acceptor structure, it relies on hydrophobic interaction for its mechanism of action: its good lipophilicity, confirmed by an oil-water partition coefficient LogP = 2.35, allows it to rapidly penetrate cell membranes, and it specifically localizes to the hydrophobic core of lipid droplets; its fluorescence is strongly enhanced in the nonpolar environment of lipid droplets, while it emits very weak fluorescence in polar environments like PBS buffer, and it exhibits a bathochromic shift in emission wavelength with increasing solvent polarity. It has negligible cytotoxicity, with cell viability remaining over 95% after 24-hour incubation with 100 μM of the probe, and it possesses excellent photostability, retaining over 97% of initial fluorescence intensity after 60 continuous laser scans. For cell imaging applications, its excitation/emission wavelengths for lipid droplet labeling are Ex/Em = 405/480−540 nm, and in a simulative lipid environment O/W emulsion, it has an excitation wavelength of ~346 nm and emission wavelength of ~500 nm, giving a Stokes shift of 154 nm[1].

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].
