“…The lowest concentration of ORZ for which a clear signal was observed was 10 nM, indicating that this CNF/WS 2 /GCE composite is effective in the electrochemical sensing of ORZ in the nM concentration levels. This compares very favourably with some of the more recently reported sensors for the detection of ORZ, with linear concentrations extending down to 10 µM with AgNPs/CPE [13], 8 µM with CuV/GCE [14], 5 µM with Ni/MoN/MC/GCE [15], 0.5 µM with a Pt/α-Fe 2 O 3 @RGO sensor [16], 0.2 µM with Co 3 O 4 /SnO 2 /GCE [17], and 0.04 with CoWO 4 /CE-BN/GCE [18]. An equally important parameter in the development of electrochemical sensors is the selectivity of the sensor.…”

It is well recognized that antimicrobials are central to society, but they have also entered the aquatic environment posing risks to public health and our essential ecosystems. Therefore, the detection of antimicrobial drugs at low concentration levels in aquatic environments is essential. In this study, a new composite comprising tannic acid modified carbon nanofibers (CNFs) and WS2 was formed to give CNF/WS2 and used in the electrochemical detection of ornidazole, an antimicrobial drug. Ornidazole is a well-known nitroimidazole and it has been detected in various water bodies. Using the CNF/WS2 composite, a linear concentration range extending from 10 nM to 260 mM ornidazole, with a sensitivity of 1.37 mA mM–1 cm–2 was obtained. Very good selectivity was achieved, and the sensor performed well in the analysis of ornidazole in river water, with recoveries ranging from 88.3 to 107.3%.
