Fig. 10From: Multiwalled carbon nanotubes decorated with bismuth (III) oxide for electrochemical detection of an antipyretic and analgesic drug paracetamol in biological samplesSWVs on B2O3/MWCNT/GCE for different paracetamol concentrations (a–i): 0.0, 0.05, 2.0, 4.0, 6.0, 10.0, 15.0, 22.0, and 28 μM in 0.1 M PBS (pH 4.0). Inset is the relationship of current responses to paracetamol concentration. Error bar = ± S.D. and 푛 = 3Back to article page
