Abstract
En 中文
• The low-cost sensor enables rapid detection of L-Trp. • MWCNT-COOH@CuONP@MgONP exhibits a synergistic effect in the electrooxidation of L-Trp. • SPCE/MWCNT-COOH@CuONP@MgONP delivers high sensitivity across wide linear ranges. • Surface analyses (SEM, EDX, FTIR, XRD, XPS) confirm the robustness of sensor fabrication. • Sensor platform matches HPLC accuracy with low detection limits.
