Summary: A new fluorescence strategy using bifunctional MOF as both a fluorescence reporter and biomimetic peroxidase was developed for ratiometric sensing of formaldehyde (FA). This strategy exhibited a wide linear range (0.1-50 mu M) and low detection limit of 0.03 mu M, and has been confirmed for FA detection in food samples. In addition to establishing a new method to detect FA, this work will open new applications of MOF in food safety.

Summary: The use of reagentless protein-based biosensors has the potential to revolutionize our understanding of biology and personalized health monitoring by directly monitoring molecular analytes in bodily fluids. Currently available molecular sensors are limited in their applicability to relevant biomarkers due to their reliance on specific enzymatic or chemical reactivity. A new class of reagentless protein-based electrochemical sensors has been introduced to overcome this limitation and enable direct measurements of biomarkers in unprocessed biological fluids. This mini-review discusses recent advances in the development of electroanalytical modular biosensors that integrate all the necessary components for autonomous functionality.

Summary: In this study, a new UiO-66 analog named UiO-66-CHO was synthesized by appending formyl on the benzene linker and further modified with alpha-naphthylamine using a covalent post-synthetic strategy. The alpha-naphthylamine functionalized MOF named UiO-66-CHO-alpha-NA exhibits excellent fluorescence property and good dispersibility. As a fluorescence probe, UiO-66-CHO-alpha-NA shows highly selectivity for the detection of Fe3+, with a detection limit of 0.54 μM comparable to other UiO-66 derived probes. The absorption competition quenching mechanism of recognition was verified through stability and UV-Vis absorption experiments.

Summary: An innovative electrochemical aptasensor based on the dual signal amplification strategy of gold nanowires and bifunctional DNA nanoflowers was designed to detect ochratoxin A (OTA). The RCA-induced bifunctional DNA nanoflowers were used for OTA detection with both target recognition and signal labeling functions. The aptasensor showed a linear range of 1 x 10(-4) to 10 ng/mL, and low limits of detection (LOD) and limits of quantification (LOQ) of 1.12 fg/mL and 3.73 fg/mL, respectively. The aptasensor demonstrated specificity, reproducibility, stability, and repeatability for OTA detection, making it a potential model for trace pollutants analysis and environmental monitoring.

Summary: A newly amino-functionalized luminescent Zr-based metal-organic framework (NU-1000-NH2) was designed for ultra-sensitive fluorescent detection of nitroaromatic explosives. The amino constructed in cavities of NU-1000NH2 can capture and bind the nitroaromatic molecules, causing fluorescence quenching due to the electron donor-acceptor interaction. The hydrogen-bonding effect between NU-1000-NH2 and analytes was also found assisting for binding and recognizing nitroaromatic explosives molecule.
