摘要
In the present work, a simple design of a "label-free" fluorescence method for kanamycin was developed and explored based on a specific DNA aptamer as a recognizer and a NMM/G-quadruplex DNA system as a reporter. The titration experiment showed a linear detection range of 0.5 to 100 nM with a low detection limit of 0.5 nM. It also showed excellent selectivity in a selectivity experiment. It was then successfully employed to detect kanamycin in milk with a excellent reliability.
