Fig. 3From: Disposable screen printed sensor for the electrochemical detection of methamphetamine in undiluted salivaCyclic voltammetry of OX1006 in the absence and presence of MAMP. The MAMP concentration was 0, 25 or 50 μg/mL MAMP (solid line, dotted line and dashed lines) in 0.1 M sodium carbonate buffer (pH 10.4), 0.2 M NaCl. 15 μL of solution was pipetted onto the sensor. The scan rate was 50 mV/sBack to article page
