Fig. 3From: Disposable screen printed sensor for the electrochemical detection of delta-9-tetrahydrocannabinol in undiluted salivaCyclic voltammetry of OX0245 in the absence or presence of Δ9-THC. 15 uL of solution containing 100 ug/mL OX0245 in 0.4 M AMPSO (pH 9.5), 1 M NaCl, 10 % methanol and (A) 0 or (B) 100 ug/mL Δ9-THC was pipetted onto the sensor. The start potential was −0.4 V and the scan rate was 50 mV/secBack to article page
