Sensitive electrochemical sensor of levofloxacin using boron-doped diamond (BDD) electrode modified with Ti3C2TX (MXene) material

Overuse of levofloxacin (LEV) is often associated with bacterial resistance and serious health problems, underscoring the need for reliable sensing and monitoring of LEV molecules. Therefore, this study aimed to investigate LEV using boron-doped diamond (BDD) and boron-doped diamond modified with MX...
