“…In recent years, our group has concentrated on the imaging and treatment of hypoxic tumors in the near-infrared region [ [45] , [46] , [47] , [48] , [49] , [50] ]. Herein, a NIR-II bioprobe Ag 2 S@PEG-ABS with PEG modified passive targeting photothermal agent Ag 2 S QDs and active targeting agent ABS was constructed and developed for inhibitor anti-tumor and photothermal synergistic therapy.…”

“…Thus far, various hydrophilic monolithic columns have been prepared, such as polyacrylamide [12][13][14][15][16][17][18][19][20], the zwitterionic [21][22][23][24][25][26][27][28], and methacrylate-based monolithic column [29]. Recently, a styrene-based polymer monolithic column with reversed-phase and hydrophilic retention mechanism was prepared by in situ polymerization of sodium p-styrene sulfonate with cross-linkers 3-(acryloyloxy)-2hydroxypropyl [30]. A polyhedral oligomeric siloxanebased zwitterionic monolithic capillary column was prepared via one-pot polymerization in ionic liquid porogen, using N,N-dimethyl-N-methacryloxyethyl-N-(3-sulfopropyl)ammonium betaine and methacrylic ethyl trimethylammonium chloride as binary functional monomers, and methacryl substituted polyhedral oligomeric siloxane as cross-linker [31].…”

A method for the preparation of poly(N-vinylpyrrolidone-co-pentaerythritol triacrylate copolymerization)-based monolithic capillary column was reported for the separation of polar small molecular weight compounds with nano-liquid chromatography in hydrophilic interaction chromatography mode. The monolithic columns were prepared by in situ copolymerization of N-vinylpyrrolidone and a cross-linker pentaerythritol triacrylate in a binary porogenic agent consisting of methanol and water. The composition of the polymerization solution was systematically optimized in terms of column permeability, theoretical plate number, asymmetric factor, and retention factor. A typical hydrophilic chromatography retention mechanism was observed with a mobile phase composed of a high content of organic solvent. The preparation method is simple and robust, the precursor N-vinylpyrrolidone is chemically stable, cheap, and easily available. The N-vinylpyrrolidone-based hydrophilic interaction chromatography stationary phase displays satisfactory separation selectivity for a range of polar test analytes, including benzoic acid derivatives, nucleosides, and phenols.

The development of the valid strategy to enhance laser desorption/ ionization efficiency gives rise to widespread concern in surface-assisted laser desorption/ ionization mass spectrometry (SALDI-MS) technology. Herein, a hybrid of Au NPdecorated graphdiyne (Au/GDY) was fabricated and employed as the SALDI-MS matrix for the first time, and a mechanism based on photothermal and photochemical energy conversions was proposed to understand LDI processes. Given theoretical simulations and microstructure characterizations, it was revealed that the formation of a coupled thermal field and internal electric field endow the as-prepared Au/GDY matrix with superior desorption and ionization efficiency, respectively. Moreover, laser-induced matrix ablation introduced strain and defect level into the Au/GDY hybrid, suppressing the recombination of charge carriers and thereby facilitating analyte ionization. The optimized Au/GDY matrix allowed for reliable detection of trace sulfacetamide and visualization of exogenous/ endogenous components in biological tissues. This work offers an integrated solution to promote LDI efficiency based on collaborative photothermal conversion and internal electric field, and may inspire the design of novel semiconductor-based surface matrices.
