8-Phenyl-BODIPY 505/515 is a molecular rotor based on the BODIPY scaffold, specifically used as a microviscosity probe. The working principle of 8-Phenyl-BODIPY 505/515 is based on the restriction of molecular motion by viscosity: in a high-viscosity environment, the rotational freedom of its chemical bonds is inhibited, which leads to a significant extension of fluorescence lifetime. This property makes 8-Phenyl-BODIPY 505/515 an effective tool for monitoring changes in the viscosity of intracellular microenvironments via fluorescence lifetime imaging (FLIM) technology .

2',7'-Difluorofluorescein (Oregon green 488) is a fluorescein derivative and a pH-sensitive fluorescent probe (pKa ~4.7). Upon excitation at 488 nm, 2',7'-Difluorofluorescein exhibits pH-sensitive fluorescence intensity through the formation of dianions, while its pH sensitivity decreases under excitation at 450 nm, allowing its use in ratiometric pH analysis. 2',7'-Difluorofluorescein can be used for the quantitative analysis of pH values in the range of 2-7 in submicron aerosol particles. 2',7'-Difluorofluorescein undergoes buffer-mediated and buffer-free excited-state proton transfer between different protonated forms, and its cationic form undergoes rapid excited-state deprotonation. 2',7'-Difluorofluorescein is resistant to photodegradation, maintains stable absorption and fluorescence properties within the physiological pH range, and serves as a fluorescent protein label, a component of Ca 2+ indicators, a fluorescent imaging agent, and an anisotropy probe .

Di-4-ANEPPS is a voltage-sensitive dye that acts on voltage-gated ion channels (such as sodium channels) and inhibits sodium current, significantly reducing sodium current density, although specific values like IC50 remain unclear. It mainly binds to the voltage-sensitive regions on the cell membrane, changing its fluorescence properties to reflect membrane potential changes and thus affecting the function of ion channels to exert its activity. This substance can be used in cardiovascular research, such as the electrophysiology of cardiomyocytes, myocardial ischemia, and the effects of drugs on cardiomyocytes. It is of great value in evaluating drug cardiotoxicity and exploring the mechanisms of arrhythmias .
