摘要：The iability in mycophenolic acid (MPA) exposure levels among organ transplant patients is substantial and directly influences the drug's therapeutic efficacy. Therefore, precise monitoring of MPA blood concentrations is imperative to devise personalized diagnostic and treatment plans tailored to individual patient profiles. In this study, we developed a screen-printed carbon electrode (SPCE) incorporating Layered Double Hydroxide-based nanozymes (LDHzymes) and multi-walled carbon nanotubes (MWCNT) to achieve high-sensitivity and stable determination of MPA in blood samples. We synthesized three distinct LDHzymes via a straightforward coprecipitation method, selecting CuMn-LDHzyme for its superior electrochemical properties and laccase activity in the context of MPA detection. The sensor's performance was enhanced by the amalgamation of CuMnLDHzyme with MWCNT, leveraging the laccase-like activity of CuMn-LDHzyme and the exceptional conductivity of MWCNT to amplify the oxidation current response to MPA. This integration significantly bolstered the sensor's detection capabilities. The developed electrochemical sensor exhibited remarkable characteristics, including high selectivity, stability, repeatability, and reproducibility. It demonstrated a notable sensitivity with a detection range of 0.5 mu M to 200 mu M for MPA, and a detection limit of 0.1 mu M, effectively detecting MPA in mouse blood samples. These attributes underscore the sensors as promising tool for clinical drug detection, ensuring fast and precise monitoring of MPA levels in organ transplant patients. This innovative approach holds significant promise for advancing personalized medical care and improving therapeutic outcomes.
