Fig. 7From: Disposable screen printed sensor for the electrochemical detection of methamphetamine in undiluted salivaCalibration plot for response to MAMP in saliva obtained from a single donor, using the 3rd peak height obtained with the split SWV technique. Each sample was tested with 12 sensors. Error bars are 1 SD. The overlayer treatment and electrochemical procedure are described in Fig. 6 Back to article page
