An Exo III-propelled stochastic 3D DNA walker based on nanosurface energy transfer was developed for enzyme-assisted DNA detection with signal amplification.
A novel electrochemical biosensor was reported for the first time to achieve highly sensitive DNA detection based on photoinduced atom transfer radical polymerization (photoATRP).
An electrochemical biosensor was developed based on the bifunctional ABs/GOxext/AuNPs/MBs-GOx@PDA magnetic PMNCs that can rapidly and sensitively detect E. coli O157:H7.
