A novel fluorescent biosensor for Adenosine Triphosphate detection based on the polydopamine nanospheres integrating with enzymatic recycling amplification

An enzymatic recycling signal amplification method for highly sensitive and selective detection of adenosine triphosphate (ATP), based on the protective performance of polydopamine nanospheres (PDANSs) for DNA against nuclease digestion and the specific recognition characteristic of aptamer.132
