A fluorescent and colorimetric probe specific for palladium detection.

A selective Pd probe is described, which shows fluorometric and colorimetric responses towards both Pd(2+) ions and Pd(0)-complexes with excellent sensitivity and potential application. The fluorescence quenching effect of Pd(2+) is inhibited by filling up d-orbitals after the reduction from Pd(2+) (open-shell) to Pd(0) (closed-shell).

A colorimetric and fluorescent merocyanine-based probe for biological thiols.

A new "dual-mode" chromogenic and fluorescent turn-on probe (2) for the selective sensing of biological thiols is reported. In MeOH-H(2)O cosolvent at physiological pH 7.40 (MeOH-H(2)O = 3:7), biological thiols cleave the 2,4-dinitrobenzenesulfonyl group to release the chromo- and fluorophore merocyanine (3).

A selective colorimetric and ratiometric fluorescent probe for hydrogen sulfide.

A reaction-based colorimetric and ratiometric fluorescent probe based on an ICT-strategy for selective detection of H(2)S that exploited the H(2)S-mediated reduction of nitrocompound to amines was explored. And it displayed high selectivity for H(2)S over other relevant reactive sulfur, oxygen, nitrogen species and other anions with more than 120 nm blue shift and the change of emission intensi...

A real-time colorimetric and ratiometric fluorescent probe for sulfite.

A real-time colorimetric and ratiometric fluorescent probe based on modulating the intramolecular charge transfer (ICT) of the coumarin platform for selective detection of sulfite is presented. This reaction based probe utilized the Michael addition to the dicyano-vinyl group with the detection limit of 5.8 × 10(-5) M. The probe displayed a high selectivity for sulfite over other anions and rea...

A colorimetric and near-infrared fluorescent probe with high sensitivity and selectivity for acid phosphatase and inhibitor screening.

A dual-channel including a colorimetric and fluorescent probe based on the aggregation-caused quenching (ACQ) and enzymolysis approach has been presented to screen acid phosphatase (ACP) and its inhibitor. Moreover, the ACP activity was determined by real time assay.
