(a) Square wave voltammetry plot of the AR released by the PNT2 cell lineage at potential range 0.0 to -0.5 V, at 40 mV amplitude, and frequency 60 Hz over time in RPMI media. (b) Signal suppression rate in signal loss percentage of the SWV peak current as the function of AR produced by the PNT2. (c) Square wave voltammetry plot of the AR released by the LNCaP cell lineage at potential range 0.0 to -0.5 V, at 40 mV amplitude, and frequency 60 Hz over time RPMI media. (d) Signal suppression rate in signal loss percentage of the SWV peak current as the function of AR produced by the LNCaP line.
