“…Figure E shows the various pHs of redox peak current responses on the modified electrode, and the results revealed that pH 7 is more favorable for APAP detection. In addition, the linear fitting of E pa and E pc vs different pHs revealed slope values of −0.0468 V/pH (oxidation) and −0.0503 V/pH (reduction) (Figure F), which are close to the actual imaginary value of −0.059 V/pH. , Hence, the optimal pH (pH 7) of 0.05 M PB would be suitable for further electrochemical analyses.…”

Nanomaterials are of significant interest in acetaminophen (APAP) detection in pharmaceutical samples. Herein, a carbon black/single-crystalline rodlike bismuth sulfide (CB/Bi2S3) composite prepared by an ultrasonic method is reported and utilized for the rapid analysis of APAP. The highly oriented edge reactive sites of the CB/Bi2S3 composite promoted synergy and good electrochemical sensing performance with a fast electron transfer rate and low overpotential (0.35 V). Therefore, a CB/Bi2S3 composite-modified glassy carbon electrode (GCE) was applied to the selective determination of APAP by the voltammetric technique. The CB/Bi2S3 composite-modified electrode showed the lowest limit of detection of APAP (1.9 nM) with excellent sensitivity. The proposed CB/Bi2S3/GCE platform exhibited high selectivity, excellent stability (87.15%), and reproducibility. Also, the CB/Bi2S3/GCE sensor was then successfully used to analyze an APAP pharmaceutical sample and exhibited satisfactory outcomes. Therefore, the CB/Bi2S3-modified GCE sensor platform would be a low-cost and robust GCE electrode material for APAP detection.

Carbon supported olivine type phosphate framework: a promising electrocatalyst for sensitive detection of dopamine

Abstract: In this study, layered olivine-type LiMnPO4/functionalized-multiwall carbon nanotubes composite is used as an electrochemically active material for the real-time detection of dopamine and extended for the detection of human serum (E48) and rat brain-serum (C7) samples.
