In this work, a novel ratiometric fluorescence nanoprobe based on Au3+-triggered aggregation-induced emission (AIE) behavior of silver nanoclusters (Ag NCs) was designed for the label-free detection of biothiols. The probe was constructed by loading of Au3+ on g-C3N4 nanosheets surface and subsequently aggregating Ag NCs via ion binding. As Au3+ could conversely regulate the emission of g-C3N4 nanosheets...
The conventional electrochemiluminescence (ECL) analyses were performed via detecting the time (or potential) dependent ECL intensity with the proceeding of ECL reaction. Herein, by spectrally recording all the photons generated in ECL process, a spectral ECL immunoassay was developed in near-infrared (NIR) region with human prostate specific antigen (PSA) as target and dual-stabilizers-capped CdTe...
A new single-isomer cationic cyclodextrin, mono-6 A -[3-(3-methoxypropyl)imidazol-1-ium]-6 A -β-cyclodextrin chloride, has been synthesized and successfully used for the chiral separation of dansyl amino acids in capillary electrophoresis. With methoxy functionality, the new cationic cyclodextrin exhibits significantly improved enantioselectivities. Excellent enantioseparations for...
A hairpin molecular beacon tagged with carboxyfluorescein in combination with graphene oxide as a quencher reagent was used to detect the DNA damage by chemical reagents. The fluorescence of molecular beacon was quenched sharply by graphene oxide; while in the presence of its complementary DNA the quenching efficiency decreased because their hybridization prevented the strong adsorbability of molecular...
An ultrathin molecularly imprinted polymer film was anchored on an Au surface for fabricating a surface plasmon resonance sensor sensitive to acephate by a surface-bound photo-radical initiator. The polymerization in the presence of acephate resulted in a molecular-imprinted matrix for the enhanced binding of acephate. Analysis of the SPR wavenumber changes in the presence of different concentrations...
