Figure 4. (А) DVPs SPE/fCNT/dsDNA and SPE/fCNT/dsDNA/Abiraterone acetate of various Abiraterone acetate concentrations. The potential range was +0,4 ÷ +1,1 V (vsAg/AgCl). Pulse amplitude of 0,025 V, step capacity of 0,005 V, interval time of 50 ms, modulation amplitude of 0,05V. (SPE – screen-printed electrode, fCNT – functionalized carbon nanotubes).
