“…In this case, however, the energy acceptor absorbs excited state energy and attenuates how much of that energy can reach the luminescent species. While such an effect has historically been seen as undesirable in that in limits emission from the target species (Thompson and Scarlata, 2019), control over the IFE based on rational system design has enabled it to be used for effective fluorescence-based sensing (Marks et al, 2015). IFE has achieved significant success in facilitating pesticide detection, mostly due to the high absorbance of the pesticide in the UV spectral region that provides an internal, (i.e.…”

The detection of pesticides in real-world environments is a high priority for a broad range of applications, including in areas of public health, environmental remediation, and agricultural sustainability. While many methods for pesticide detection currently exist, the use of supramolecular fluorescence-based methods has significant practical advantages. Herein, we will review the use of fluorescence-based pesticide detection methods, with a particular focus on supramolecular chemistry-based methods. Illustrative examples that show how such methods have achieved success in real-world environments are also included, as are areas highlighted for future research and development.

“…Several analytical techniques have been developed for the detection of H 2 O 2 including colorimetric, [ 3 ] electrochemical method, [ 4 ] surface enhanced Raman [ 5 ] and fluorimetry. [ 6 ] Among them, electrochemical technique with the inherent advantages of high sensitivity, low‐cost, simple operation, quick response and facile miniaturization, has been one of the most promising strategies. Enzyme‐ based electrochemical biosensors have high selectivity and efficiency in the detection of H 2 O 2 .…”

Cu-based metal organic frameworks (MOFs) are regarded as promising sensing materials, which have abundant metal sites, large surface area and simple synthesis processes. In this work, a novel three-dimensional flower-like Cu-MOF was synthesized, which was combined with ultra-thin MXene nanosheets to construct a novel electrochemical sensor for H 2 O 2 . During the electrocatalytic reduction of H 2 O 2 , the catalytic activity of Cu-MOF/MXene/GCE results in the ultra-sensitive detection of H 2 O 2 owing to the structure properties of MOFs, the nature of Cu-contained nanomaterials as well as the high electrical conductivity of MXene. The Cu-MOF/MXene/GCE showed a wide linear range from 1 mol/L to 6.12 mmol/L using chronoamperometry at the detection potential of -0.35 V, and the detection limit is estimated to be 0.35 µmol/L. The sensor also shows good anti-interference due to the lower detection potential, specific catalysis of Cu-MOF to H 2 O 2 , which promises the sensor good selectivity in complexed samples. Meanwhile, the electrochemical sensor is capable to detect H 2 O 2 in milk and serum samples with satisfactory recoveries. The ultra-sensitivity, rapid detection, and easy operation of the proposed sensor present significant prospect for real-time analysis and monitoring of H 2 O 2 in foods and biological samples.

Eight novel fluorescent conjugated polymers were synthesized by the Suzuki polycondensation reaction of 9,9-dioctylfluorene-2,7-diboronic acid bis(1,3-propanediol) ester and a conjugated dihalogenated monomer. The photophysical properties of these polymers were investigated as welldissolved solutions in chloroform and as nanoparticle suspensions in water. Several of the polymers had large Stokes shifts (greater than 100 nm) and others demonstrated unique changes in the fluorescence properties in aggregated verse non-aggregated forms. Preliminary applications of these polymers in the detection of common bisphenols are also reported.Click here to insert a dedication.
