“…Therefore, we chose cola, milk, nori, and urine to represent the intake and output of Iodine. According to the previous literature, we carried out pretreatment on milk samples and urine samples. , To prepare the analytical nori sample, we grind the nori sample in a mortar and take 0.1 g of nori powder and add it to 30 mL of 95% ethanol solution, extract at 80 °C for 10 min, filter it, and then dilute the filtrate with PBS (pH 6.8) to 50 mL for later use.…”

In this study, the zeolitic imidazolate framework (ZIF-8) and glutathione silver nanoclusters (GSH-AgNCs) were assembled by the in situ synthesis method to form nanomaterials (GSH-AgNCs-ZIF-8). Meanwhile, a luminescent functional assembly of nanocomposites with adjustable potentials and luminescence enhancement was gained through innovative mixing of the luminophores tetracarboxyphenyl zinc porphyrin (TCPP-Zn) and GSH-AgNCs-ZIF-8. Composition and morphology of the materials were studied by electrochemistry and spectroscopy techniques. The blended material was used as high-efficiency luminophore to build the electrochemiluminescence (ECL) sensing system for iodide ion (I − ) detection whose ECL mechanism has also been studied in depth. Under optimization conditions, ECL sensors showed excellent responses to I − in the linear range from 10 pM to 10 μM. This detection method showed selectivity, stability, and sensitivity. Moreover, it achieved relatively satisfying results to iodide ion detection in cola, milk, nori, and urine samples. This research not only develops and applies functional nanomaterials, but also establishes an ECL sensor system and provides ideas for the detection of micromolecules in food and clinical testing.

“…Recently, Afshary et al reported a PIM-1 nanoparticle/nitrogen-doped carbon quantum dot electrochemiluminescence (ECL) sensor to detect citrate ions as a prostate cancer biomarker. 218 Electrochemiluminescence intensity was quenched with increasing citrate concentration. The detection limit of the sensor was calculated to be 2.21 M. The sensor has also been used successfully to detect citrate levels in human serum and urine.…”

Polymers of intrinsic microporosity (PIMs), with an interconnected microporous network, high surface area, and structural diversity, have attracted great interest in developing diverse materials for various applications in the fields of environmental remediation, gas and liquid separation, sensors, and energy. Solution-processable PIMs can be transformed into various robust functional materials, including films, membranes, coatings, and fibers, that can be applied to address different industrial challenges. Since the first PIM synthesis, great strides have been made in expanding the structural diversity of PIMs by designing fine-tuned PIMs for various applications. This review provides a general overview of PIMs, from their synthesis to their involvement in state-of-the-art applications such as water and air filtration, gas and liquid separation, catalysis, sensing, and energy applications, during the last decade. Several PIMs have exhibited outstanding performance in oil adsorption, gas separation, and catalysis. In this context, PIMs' functionality and porosity are key parameters that must be controlled to tailor PIMs for broader applications. Overall, this review provides a comprehensive overview of PIMs from chemistry to applications and highlights the challenges and prospects of the next generation of PIM-based functional materials that will open new avenues for adsorption, gas separation, and filtration applications.
