Summary: This study investigates the thermal expansion of the metal-organic framework (MOF) PCN-222 using powder X-ray diffraction under variable temperature. The results show that the thermal expansion increases significantly with more aggressive heating, attributed to enhanced flexibility after guest removal. Furthermore, the thermal response exhibits strong temperature dependence, with a nearly quadruple volumetric expansivity and a change in the expansion direction along c upon cooling. These findings highlight the high flexibility of MOFs and the significance of guest species.

Summary: A new biosensing platform for HPV-16 virus detection was developed using PCN-224/nano-zinc oxide composites, cyclic amplification, and hybridization chain reaction. The stability of the electrode was improved by introducing a hybrid substrate material based on PCN-224, nano-zinc oxide, and polyacrylamide. The amplification efficiency of the target HPV-16 was greatly enhanced, and the signal-off detection of HPV was achieved through cycling cleavage and HCR-amplified signal.

Summary: Ru-PEI-L-lys was immobilized on ZIF-8 to form Ru-PEI-L-lys-ZIF-8, which was then mixed with PtNPs to enhance the ECL response. The combination of selective aptamer and RecJf exonuclease in the system resulted in a highly sensitive ECL biosensor for thrombin detection, with a linear response range from 1 fM to 10 pM and a detection limit of 0.02 aM. This work presents a new strategy for designing stable ECL indicators and developing sensitive ECL sensors for biological analysis.

Summary: The study presents a strategy for preparing mixed-valence Ce-MOF nanowires using a micelle-assisted biomimetic route, demonstrating good water stability and high conductivity. These nanowires were successfully applied in the design of an ECL sensor for detecting trace amounts of imidacloprid in plant-derived foods. The research not only proposes a novel route for downsizing MOFs but also provides a facile and robust methodology for designing MOF-based molecular imprinting ECL sensors.

Summary: Cathodic photoelectrochemical (PEC) sensors are urgently required for ultrasensitive environmental monitoring, and porphyrin-based covalent organic framework (TAPP-COF) thin films were fabricated and applied in this study. By utilizing CdSe@SiO2 quantum dots as a quenching agent and introducing target Pb2+, accurate monitoring with a wide detection range and low detection limit was achieved through an on-off-on PEC approach. This methodology provides an efficient platform for ultrasensitive determination of heavy metal ions, contributing significantly to environmental monitoring and public safety.

Summary: This study investigates the application of 3D-printed bioceramics in bone tissue engineering. By depositing PCN-224 onto 3D-printed porous C2S scaffolds, composite scaffolds with uniform large pores are obtained. These scaffolds significantly promote cell proliferation and the expression of osteogenesis-related genes, while showing a slower degradation rate. Compared to single C2S scaffolds, the composite scaffolds greatly improve the healing of calvarial defects in rats.
