“…To this end, various analytical methods have been deeply investigated for reporting the levels of residual FQs in actual agri-food, medicine, and environmental samples, such as chemiluminescence (CL), Fourier transform infrared (FT-IR) spectroscopy, high-performance liquid chromatography (HPLC), microbiological assay, fluorescence spectroscopy, , electrochemistry, immunoassay, capillary electrophoresis (CE), atomic absorption spectrometry (AAS), and surface-enhanced Raman spectroscopy (SERS) . Although the above technologies have satisfactory selectivity and sensitivity to the FQ response, they also have some unavoidable drawbacks, including requiring bulky apparatus, professional technical personals, a complex fabrication process of the response system, high cost, and long time, due to which they fail to meet the requirements of onsite quantification in practical food-related industries as well as environmental concerns, especially in case of emergencies.…”

Accurate onsite profiling of fluoroquinolone antibiotics (FQs) is of vital significance for ensuring food safety and estimating environmental pollution. Here, we propose a smartphone-based QD ratiometric fluorescence-sensing system to precisely report the level of FQs. As a proof of concept, we chose gatifloxacin (GFLX, a typical member of FQs) as the model for the analytical target, which could effectively trigger the fluorescence color variation of QDs from bright yellow-green (∼557 nm) to blue (∼448 nm) through the photoinduced electron-transfer (PET) process, thus yielding an evident ratiometric response. Based on this, the level of GFLX can be reported within a wide linear range from 0.85 nM to 3.6 μM. Moreover, this assay owns a high sensitivity with a low detection limit of 0.26 nM for GFLX and a quick sample-to-answer monitoring time of 5.0 min, manifesting that this platform could be fully qualified for onsite requirements. Interestingly, this portable device has successfully been applied for the onsite detection of GFLX in real food (i.e., milk and drinking water) and environmental (i.e., fish-farming water) samples with acceptable results. This developed platform offers a great promise for the point-of-care detection of FQ residues in practical application with the merits of being label-free, low-cost, and rapid, thus opening a new pathway for the onsite evaluation of food safety and environmental health.

“…Therefore, the development of effective FQs detecting method is urgent. Compared with instrumental analysis method, fluorescence FQ detection may be a promising method due to its high sensitivity and simple sample preparation procedures. Therefore, it is important to develop luminescent CPs as the sensor for EX detection.…”

Three metal–organic coordination polymers, [M(2,6‐bip)2] (M = Zn (1), Ni (2)) and [Cu (tfbdc)(2,6‐bipH)2]•2H2O (3), were obtained with the similar solvothermal reaction systems of bivalent transition metal salt, 6‐(1H‐imidazol‐1‐yl)‐2(1H)‐pyridinone (2,6‐bipH) and 2,3,5,6‐tetrafluoroterephthalic acid (H2tfbdc). The three coordination polymers show different framework features, namely 3D (1), 2D (2) and 1D (3) structures, which are resulted from different single‐metal ion “node” and “linker” coordination modes. The [ZnO2N2] tetrahedron in 1 and [NiO2N4] octahedron in 2 as a node, is formed from Zn sp3 and Ni d2sp3 hybrid orbits, respectively, while the linker, 2,6‐bip, adopts the μ2:η1η1η0 in 1 and μ2:η1η1η1 in 2 coordination modes. PLATON calculation suggests that 1 possesses the micropore structure with a pore volume of 14.2%. In 3, the [CuO2N2] parallelogram as a node is derived from Cu dsp3 hybrid orbital, while the linkers of 2,6‐bipH and tfbdc adopt the μ1:η1η0η0 and μ1:η1η0/μ1:η1η0 coordination modes, respectively. Intriguingly, Zn(d10)‐centre coordination polymer 1 shows strong blue emission, which are derived from the π* → π transition of the 2,6‐bipH ligand. Moreover, 1 exhibits high stability and strong luminescence in both water and ethanol. At this point, the performance of 1 is studied as a chemical sensor for detecting fluoroquinolones drug. The results show that 1 can detect enoxacin in ethanol solution with a low detection limit of 3.61 × 10−5 M. The luminescent sensing mechanisms were investigated from experimental methods and theoretical calculation in detail as well.
