Summary: To achieve fast, convenient, and highly sensitive detection of microRNA (miRNA), palladium-gold (Pd-Au) bimetallic nanoplates with high photothermal effect were synthesized and combined with locked nucleic acid (LNA) detection probe to develop a photothermal lateral flow locked nucleic acid biosensor (P-LFLNAB) for miRNA detection. The P-LFLNAB enables sensitive and selective miRNA-21 detection with detection limit down to 0.094 pM using a smartphone with external thermal imager, which is 639.5 times lower than that of the conventional gold nanoparticles based colorimetric lateral flow biosensor and the most sensitive enzyme-free lateral flow biosensor for miRNA detection. Besides, the P-LFLNAB achieved single-base mismatch discrimination and can quantify signals in various cell lysates. This highly sensitive, selective and portable P-LFLNAB with smartphone readout has great potential in point-of-care test of miRNAs-related biomedical application.

Summary: In this study, we report the design of a Ti-based metal-organic framework (MIL) and silver nanoparticles (Ag NPs) heterostructure, MIL@Ag. It is found that the introduction of Ag NPs significantly improves the electron transfer efficiency and O2 adsorption capacity of MIL, leading to enhanced reactive oxygen species (ROS) generation for sonodynamic therapy (SDT). Under ultrasound irradiation, the activated electrons and holes from MIL and Ag NPs produce superoxide radicals and hydroxyl radicals, respectively, improving the therapeutic efficiency of SDT. MIL@Ag-PEG-mediated SDT demonstrates effective cancer cell killing and bacterial infection eradication. Thus, MIL@Ag-PEG provides a promising strategy for enhancing SDT performance through rational heterostructure design of sonosensitizers.
