Abstract:
To address the challenge of recognizing lomefloxacin (LMF) residues in the environment and food, this work describes the development of a molecularly imprinted electrochemical sensor (MIECS) that combines a 3D Ti3C2Tx/Ni(OH)2 composite with molecularly imprinted polymers (MIPs). The 3D Ti3C2Tx/Ni(OH)2 framework has a larger surface area and more active sites, allowing for efficient electron and ion transport. Meanwhile, pyrrole, which serves as the functional monomer for MIP synthesis, adds imide functional groups and strong proton conductivity, considerably improving the sensor's particular identification capacity for LMF. The MIECS's sensitivity and selectivity are further enhanced by a potent synergistic interaction between these components. The sensor's exceptional recognition capability toward LMF. A wide linear response was recorded spanning the concentration range of 0.5 to 105 nM, having the limit of detection as low as 0.0157 nM, alongside remarkable stability and anti-interference performance. The sensor also delivered consistent recovery rates in real sample analyses-such as milk and lake water-validated by comparative studies with liquid chromatography. The use of 3D Ti3C2Tx-based MIECS in ultrasensitive antibiotic monitoring is made possible by this work.
