چکیده
A novel single-labeled fluorescent oligonucleotide (OND) probe for the detection of nanomolar silver(I) ion in aqueous solution is developed based on the inherent quenching ability of deoxyguanosines. The formation of a hairpin structure of the OND-Ag(+) complex brings deoxyguanosines close to a dye, leading to a decreased fluorescence intensity of the dye owning to photoinduced electron transfer from the dye to deoxyguanosines.

A New Colorimetric Azo-azomethine Probe for Fluoride Ion Detection Based on the Proton Transfer Signaling Mode: Real-life Applications
Four novel receptors were designed and synthesized for colorimetric detection of F− ions. The introduction of four electron withdrawing groups into the backbone of the receptors makes the two phenolic groups efficient hydrogen bonding sites. The binding properties of receptors with anions were examined for the first time by UV–Vis, 1H NMR and fluorescence spectroscopies. The addition of F− resu...
متن کاملHighly sensitive and selective detection of silver(I) ion using nano-C60 as an effective fluorescent sensing platform.
In this Communication, we report water-soluble nano-C(60) in the first use as an effective fluorescent sensing platform for the highly sensitive and selective detection of Ag(+). The general concept used in this approach is based on a fluorescently labeled single-stranded DNA (ssDNA) probe that adsorbs on nano-C(60), leading to substantial dye fluorescence quenching; however, in the presence of...

متن کاملFluorescence-quenching phenomenon by photoinduced electron transfer between a fluorescent dye and a nucleotide base.
Fluorescently labeled oligonucleotide probes have been widely used in biotechnology, and fluorescence quenching by the interaction between the dyes and a nucleobase has been pointed out. This quenching causes big problem in analytical methods, but is useful in some other cases. Therefore, it is necessary to estimate the fluorescence quenching intensity under various conditions. We focused on th...
