Summary: This study successfully embeds highly dispersed ultrasmall Ru nanoparticles onto carbon nitride (C3N4) nanosheets through a spontaneous redox reaction, forming Ru-C3N4 nanocomposites. The Ru-C3N4 exhibits excellent peroxidase-like activity, which can be regulated by adjusting the loading of Ru nanoparticles. A colorimetric sensing method for alkaline phosphatase (ALP) detection is developed based on the inhibitory effect of ascorbic acid on the color development reaction of Ru-C3N4. The sensor shows a wide linear range and low detection limit for ALP sensing, and satisfactory results are obtained in detecting ALP in human serum.

Summary: In the pursuit of chiral materials with significant chiral recognition effects and stability, the integration of metal nanoparticles and chiral metal-organic frameworks (CMOFs) has shown promise. However, the combination of metal nanoparticles (MNPs)/CMOFs often suffer from inferior stabilities due to the detachment of MNPs under certain conditions. To overcome this, a novel sandwich chiral material (D-His-ZIF-8@ Au@ZIF-8) was synthesized, which demonstrated excellent chiral recognition capabilities. This experiment presents a new perspective for the fabrication of a chiral electrochemical sensing platform based on a solid sandwich chiral nanocomposite.

Summary: Fluorescence-guided phototherapy is an emerging noninvasive cancer treatment strategy. Organic molecules, with their easy construction, simple modification, and good biocompatibility, have shown promise as theranostic agents. This study successfully developed a versatile theranostic platform based on an aggregation-induced emission luminogen, TPA-TBT, which exhibited near-infrared emission, high fluorescence quantum yield, robust reactive oxygen species production, and excellent photothermal conversion efficiency. In vivo studies demonstrated its outstanding efficacy in both photodynamic and photothermal therapies against tumors in a mouse model. This work provides a design strategy for developing all-in-one cancer theranostic agents by modulating and utilizing the relaxation energy of excitons.
