A new electrochemical platform for ultrasensitive detection of atrazine based on modified self-ordered Nb2O5 nanotube arrays

In the present work, we develop a new electrochemical sensing platform for detecting trace amount of ATZ by using Fe3O4 NPs and CS modified Nb2O5 nanotube arrays. This 1D composite electrode exhibits a low detection limit and good reproducibility, which indicates that the Nb2O5 nanotube arrays are promising candidates for electrochemical sensors.222
