Molecularly imprinted polypyrrole decorated Ti3C2Tx electrochemical sensor for highly selective and sensitive detection of levofloxacin
Herein, a rapid and efficient molecular imprinted polymer (MIP) modified Ti3C2Tx-based electrochemical sensing platform was developed for levofloxacin detection (LEV). The MIP sensor was designed by depositing the synthesized Ti3C2Tx electrophoretically onto the indium tin oxide (ITO) glass surface, followed by electropolymerization of pyrrole as a monomer and LEV as a template molecule. Ti3C2Tx significantly enhances the electron transfer rate and offers a larger surface area to increase the number of imprinted sites for precise recognition of LEV. The fabricated sensor (MIP/Ti3C2Tx/ITO), under all optimized parameters, demonstrated superior selectivity with a low detection limit (LOD) of 0.76 pM and a linear relationship with LEV concentration ranging (1 pM–100 nM). Additionally, this newly developed sensor exhibited robust stability and sensitivity and successfully detected LEV in actual samples with satisfactory outcomes.
