A new generation of photothermal theranostic agents is developed based on Cu3BiS3 nanocrystals. A computed tomography imaging response and photothermal effect, as well as near-infrared fluorescence emission, can be simultaneously achieved through Cu3BiS3 nanocrystals rather than frequently used nanocomposites. These results provide some insight into the… (More)
A versatile nanoplatform of FeWO4@Polypyrrole (PPy) core/shell nanocomposites, which was facilely fabricated by first hydrothermal synthesis of FeWO4 nanoparticles and subsequent surface-coating of polypyrrole shell, was developed as an effective nanotheranostic agent of cancer. The as-prepared nanocomposites demonstrated excellent dispersion in saline,… (More)
We report a facile and low-cost approach to design a difunctional nanoplatform (CuS@mSiO2-PEG) as a near-infrared (NIR) light responsive drug delivery system for efficient chemo-photothermal therapy. The nanoplatform demonstrated good biocompatibility and colloidal stability, as well as high loading capacity for the anticancer drug (26.5 wt% for doxorubicin… (More)
A series of acyclic oligourea receptors which closely resemble the scaffolds and coordination behavior of oligopyridines have been synthesized. Assembly of the receptors with chloride ions afforded mononuclear anion complexes or dinuclear foldamers depending on the number of the urea groups.
N-Phenyl-N'-(3-quinolinyl)urea (1) has been developed as a highly selective colorimetric and ratiometric fluorescent chemosensor for fluoride ion based on a proton transfer mechanism. Evidences for the mechanism were provided by UV-vis and fluorescence titration and especially (1)H and (19)F NMR experiments. The sensor gave the largest ratiometric… (More)
Three ferrocenyl-functionalized tripodal hexaurea anion receptors with ortho- (L(2)), meta- (L(3)), and para-phenylene (L(4)) bridges, which showed strong binding affinities toward sulfate ions, have been designed and synthesized. In particular, meta-phenylene-bridged ligand L(3), owing to its trigonal bipyramidal structure, can encapsulate two SO4(2-) ions… (More)
Survivin, a member of the inhibitor of apoptosis gene family regulates two critical processes in neoplastic transformation, namely, cell proliferation and apoptosis. This study aimed to detect the effect of survivin on tumor growth of colorectal cancer (CRC) in vivo. We found that inhibition of survivin by interference decreased the sizes and weights of… (More)
Metal oxides are receiving an incremental attention in recent years for their potential applications in ablation of cancer cells due to their efficient photothermal conversion and good biocompatibility, but the large sizes and poor photo-stability will seriously limit their practical application. Herein, hydrous RuO2 nanoparticles were synthesized by a… (More)
Two anion receptors with the same tripodal scaffold but different signaling groups are employed to control intermolecular anion transfer via an electrochemical stimulus, which is detected by the change of the fluorescence intensity before and after electrochemical oxidation of the ferrocenyl units.
