Amplifying fluorescent signals in molecular sensing with DNA walkers

NanoWerk.com - Mon, 08/21/2017 - 07:48
Synthetic nanomotors and DNA walkers, which mimic a cell's transportation system, are intricately designed systems that draw chemical energy from the environment and convert it into mechanical motion. Using such DNA walkers as signal amplifier for nucleic acids detection has only recently been reported. Researchers now report that they converted a DNA walker into a linear fluorescence signal amplifier on a rectangle DNA origami that can improve the detection of target molecules such as nucleic acids.
