Abstract:
A simple and facile strategy was developed for regulating the luminescence of Tb(3+) sensitized by DNA, in which Ag(+) and cysteine (Cys) act as activators. The Ag(+)/Cys-mediated reversible luminescence changes in the Tb(3+)-DNA sensing system enabled the design of a DNA INHIBIT logic gate and a H2O2 sensor in a time-resolved luminescence format.

03:31Labeling DNA Probes
7.7K
DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Microbial biosensors are analytical devices that utilize living microbes to detect specific substances through measurable signals. These devices consist of two main components: biosensing organisms and signal-transducing elements. Biosensing organisms, such as Escherichia coli or Saccharomyces cerevisiae, are typically housed in multiwell plates connected to transducers, enabling rapid, real-time detection of target analytes.Signal Generation MechanismWhen a target analyte—such as...
