Wiem Bouali et al.

Summary: This research presents a modified glassy carbon electrode with platinum nanoparticles anchored on reduced graphene oxide nanocomposite as a conductive modifier (Pt@rGO/ GCE) for the detection of Favipiravir (FAV), an anti-coronavirus drug. The nanocomposite was characterized using various techniques and the square wave voltammetry (SWV) method was used to determine FAV in real samples. The electrode demonstrated a wide linear concentration range and a low detection limit, as well as exceptional selectivity and repeatability in the presence of interferences.

Summary: Favipiravir is an antiviral drug used for treating pulmonary infections and lung inflammation in COVID-19 patients. An electrode modified with ILCs and CNTs has been developed for sensitive and selective detection of Favipiravir in human serum and medications. The electrode allows for the preconcentration of the drug on its surface, with detection and quantification limits for Favipiravir in blood serum of 0.0161 and 0.119 μmol L-1 respectively. The sensor is also effective for concurrent determination of multiple drugs used for virus treatment or other chronic diseases.
