Visual detection of mercury(II) based on recognition of the G-quadruplex conformational transition by a cyanine dye supramolecule.
نویسندگان
چکیده
A supramolecular probe for visual detection of mercury (Hg) has been designed by using a cyanine dye and AS1411 G-quadruplexes, which exhibits an obvious color change from red to blue in response to an increased level of Hg(2+). The supramolecular probe exhibits high selectivity and sensitivity towards Hg(2+) and is promising for the detection of environmental samples with the naked eye.

Visual detection of potassium by a cyanine dye supramolecular aggregate responsive to G-quadruplex motif transition.
A supramolecular probe is designed for visual detection of potassium based on a novel cyanine dye aggregate recognizing the motif transition of telomeric G-quadruplexes under the Na(+) background. The practical application for colorimetric measurement of urine potassium has been tested.
متن کاملA dual-site simultaneous binding mode in the interaction between parallel-stranded G-quadruplex [d(TGGGGT)]4 and cyanine dye 2,2′-diethyl-9-methyl-selenacarbocyanine bromide
G-quadruplexes have attracted growing attention as a potential cancer-associated target for both treatment and detection in recent years. For detection purpose, high specificity is one of the most important factors to be considered in G-quadruplex probe design. It is well known that end stacking and groove binding are two dominated quadruplex-ligand binding modes, and currently most reported G-...
متن کاملCyanine Dye Interactions with Quadruplex and Duplex DNA: Changes in Conformation, Stability, and Affinity
There is a high demand for quadruplex-specific compounds that not only bind preferentially to quadruplex DNA over duplex DNA, but also bind to one quadruplex motif over other motifs. Quadruplex structures are recognized as common occurrences in cancer cells, and if a compound could stabilize this structure, it may serve as an effective anti-cancer treatment with minimal side effects. In this st...

متن کاملTargeting of parallel c-myc G-quadruplex by dimeric cyanine dye supramolecular assembly: dependence on the linker length.
A series of dimeric cyanine dyes were designed to study their recognition for parallel c-myc G-quadruplex as well as their spectral features in solution. Dimeric cyanine dyes having different length linkers show their recognition for c-myc over duplex DNAs following the order: TC-P4 > TC-P5 > TC-P6 > TC-P3 > TC-P7 [the numeral is the number of repeat units (oligo-oxyethylene) in the linker]. Th...
