This study employed a novel synthetic approach involving a modified reverse co-precipitation
method utilizing glacial acetic acid to synthesize α-Bi2O3
. X-ray powder diffraction and scanning and
transmission electron microscopy analyses revealed the formation of a rod-like α-Bi2O3 microstructure. The prepared material was utilized to modify a glassy carbon paste (GCP) electrode for the
development of an electrochemical sensor for acetaminophen (APAP) detection using differential
pulse voltammetry (DPV). Cyclic voltammetry studies revealed that the GCP@Bi2O3 electrode exhibited enhanced electrochemical properties compared to the bare GCP. The designed GCP@Bi2O3
sensor detected APAP in the linear concentration range from 0.05 to 12.00 µM, with LOQ and LOD of
36 nM and 10 nM, respectively. Additionally, the developed sensor demonstrated sufficient precision,
repeatability, and selectivity toward APAP detection. The recovery values between the declared
and found APAP content in a pharmaceutical formulation (Caffetin®) displayed the advantageous
accuracy, precision, and applicability of the GCP@Bi2O3 sensor and the developed DPV method for
real-time APAP detection in pharmaceuticals, with minimal interference from the matrix effect.
