1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7) belongs to piperazine derivatives. Piperazine causes primary dermal irritation and skin burns at high concentrations. Piperazine also causes eye irritation in humans. Outside the body, piperazine has a remarkable power to dissolve uric acid and producing a soluble urate, but in clinical experience it has not proved equally successful.

The abuse of antibiotics would seriously affect human health and has become of worldwide critical concern, thus it is urgent to develop an environmentally friendly and nontoxic fluorescent probe for antibiotics sensing. In this work, a lead-free Cs2ZnCl4 perovskite nanocrystals (PNCs) probe was fabricated for sensing norfloxacin (NOR) employing a modified ligand-assisted reprecipitation method. The prepared Cs2ZnCl4 PNCs probe had strong blue emission around 440 nm, and the characteristics of PNCs were systematically characterized by X-ray photoelec. spectroscopy (XPS), Fourier transforms IR spectroscopy (FTIR), transmission electron microscope (TEM) and powder X-ray diffraction (XRD). The results revealed that the fluorescence intensity of the Cs2ZnCl4 PNCs was significantly enhanced after the introduction of norfloxacin. The Cs2ZnCl4 PNCs can be used as a fluorescent probe to selectively and sensitively detect norfloxacin in the concentration range from 0.2 to 50.0 μM, with a correlation coefficient (R2) of 0.9954 and the limit of detection (LOD, 3σ) of 0.1499 μM. The preparation and application of a lead-free perovskite fluorescent probe for norfloxacin would promote the application of perovskite fluorescent probes in biochem. assays. This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Product Details of 70458-96-7).
