A sensitive electrochemical sensor for the detection of sports stimulant methyltestosterone via ZnO/TiO2 nanocomposite

This research paper introduces a highly sensitive electrochemical sensor designed for the detection of the sports stimulant methyltestosterone, utilizing a unique ZnO/TiO 2 nanocomposite. Methyltestosterone, an extensively abused anabolic steroid in sports, calls for an efficient detection technique to maintain sporting integrity. The sensor was designed and synthesized with enhanced properties leveraging the specific characteristics of the ZnO/TiO 2 nanocomposite. The sensor demonstrated high sensitivity and selectivity towards methyltestosterone, outstripping traditional detection techniques. When subjected to real-world scenarios, including testing in synthetic urine samples, the sensor showcased outstanding precision and consistency, making it a robust tool for anti-doping control.
