Sensitive voltammetric determination of baicalein at DNA Langmuir–Blodgett film modified glassy carbon electrode

The present paper describes to modify a double stranded DNA–octadecylamine (ODA) Langmuir–Blodgett film on a glassy carbon electrode (GCE) surface to develop a voltammetric sensor for the detection of trace amounts of baicalein. The electrode was characterized by atomic force microscopy (AFM) and cy...
