Abstract:
We have developed a novel fluorescence-activated DNA-MoS2 nanosheet biosensor for detecting biomolecular targets such as proteins and small molecules based on the self-assembled architecture of a DNA aptamer and a MoS2 nanosheet. The proposed design is simple to prepare and exhibits low background interference, high sensitivity and rapid response.
