Accurate and sensitive determination of SRT is essential for therapeutic drug monitoring, dose optimization, pharmacokinetic studies, and the prevention of adverse effects associated with inappropriate drug exposure. In this study, a simple and sensitive electrochemical sensing platform was developed for the determination of SRT, achieving a detection limit at nanomolar levels. The sensor was fabricated by modifying the SPCE surface with feather\u2010like Au\u2212Ag\u2212CoO\n                    <jats:sub>\n                      <jats:italic>x<\/jats:italic>\n                    <\/jats:sub>\n                    \u2010based multicomponent composite materials, which provided an enhanced electroactive interface for SRT oxidation.

The sensor also exhibited good selectivity against the testing interfering species, along with excellent repeatability and reproducibility, with RSD values of 1.46% and 1.75%, respectively, and acceptable long\u2010term stability by retaining approximately 85% of its initial response after 30 days. The practical applicability of the method was demonstrated through the analysis of SRT in pharmaceutical tablets, human serum, and water samples, yielding recovery values of 98.71%\u2013102.35%, 97.45%\u2013104.29%, and 100.80%\u2013104.00%, respectively.
