1 results about "Sodium fluorescein" patented technology

This invention discloses a dual-emission fluorescent nano-assembly, its preparation method, and its application in ATP detection. The co-assembly achieves the detection of adenosine triphosphate (ATP). This invention uses an amphiphilic TPE derivative as the energy donor and an amphiphilic imidazole compound as the anion acceptor to form a dual-emission fluorescent nano-assembly with sodium fluorescein. Significant energy transfer occurs, resulting in strong fluorescence from the sodium fluorescein. After sodium fluorescein is replaced by ATP, the donor regains strong fluorescence emission while the light from the sodium fluorescein is quenched, allowing for the fluorescence detection of ATP with a detection limit as low as 0.735 nM. This method is simple, sensitive, and enables rapid and accurate specific quantitative detection of ATP, and can be widely used in the biomedical field.
