Fluorescent Dye

Fluorescence is a phenomenon of photoluminescence in luminescence. When an atom is irradiated by light, some electrons around the nucleus jump from their original orbitals to higher energy orbitals under the influence of light energy, i.e., from the ground state to the first or second excited single-line state, etc. Due to the instability of the first or second excited singlet state, the electron returns from the excited singlet state to the ground state accompanied by released energy, resulting in fluorescence.

Fluorescent dyes can be covalently bound or physically adsorbed in the structure of the substance. The fluorescence properties allow for the characterization, localization and quantitative analysis of the labeled object. Fluorescent dyes have shown great potential for the detection of proteins, nucleic acids, cells, and immunoassays, attributed to the advantages in non-radioactive contamination, simple experimental operation and easy observation.

Fluorescent dyes have penetrated many fields such as pharmacology, physiology, environmental science, and information science, as well as functional studies of proteins and drug screening.

    TPE-PY
    TPE-PY is a fluorescent dye targeting mitochondria, which has cationic and lipophilic characteristics, enabling specific targeting of mitochondria. TPE-PY functions through the aggregation-induced emission (AIE) mechanism. TPE-PY mechanism of action is based on the restriction of intramolecular rotation (RIR), which enhances fluorescence in the aggregated state. TPE-PY is mainly used in the field of biological imaging, especially for the specific staining of mitochondria in living cells, facilitating the observation of the location, morphology, and quantity of mitochondria.
