title: "DNA traffic lights": concept of wavelength-shifting DNA probes and application in an aptasensor.
abstract: Add it and see it: The concept of "DNA traffic lights" for wavelength-shifting DNA probes has a great potential in the application of biosensors, for example, in DNA aptamers. A visual color change in the DNA aptasensor fluorescence from green to red occurs after specific target binding.
