Summary: Elaboration of photonic based sensors is a highly promising direction in modern analytical chemistry, particularly for clinical applications. The sensors based on photonic integrated circuits (PICs) demonstrate the highest sensitivity and have been successfully combined with microfluidics to decrease the analyte volume. Despite this, these sensors suffer from low specificity, which can be addressed by layer by layer (LBL) assembly. The ability to precisely control surface modification using measurements of minimum resonance position shift was demonstrated. These PIC based sensors have great potential for in situ control of surface modification and can be used in point-of-care devices for early pathological state diagnosis and treatment evaluation.

Summary: Photothermal and photodynamic therapies (PTT and PDT) can activate antitumor immunity and suppress metastatic tumors by inducing immunogenic cell death (ICD). However, mono-PTT or mono-PDT are generally insufficient and tumor microenvironment can offset the antitumor effects. In this study, a hollow germanium nanosphere (HGNs) with favorable photothermal and photodynamic effects was developed, promoting ICD of tumor cells and reversing immunosuppressive tumor microenvironment. HGNs effectively eradicated both primary and distant tumors and improved animal survival, showing great potential for clinical translation.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
