Integrated pharmaceutical innovation experiment： preparation of molecularly imprinted polymers and the application in sample pretreatment for in vivo drug analysis

Under new pharmaceutical science initiatives and innovation training， we address complex biological sample analysis. A comprehensive pharmaceutical experiment was designed for this purpose. It integrates pharmaceutical analysis， polymer chemistry， and analytical chemistry. Advanced molecular imprinting technology （MIT） serves as the key tool. Cholic acid， a significant endogenous metabolite， is selected as the template. Cholic acid molecularly imprinted polymers （CA-MIPs） are synthesized via precipitation polymerization. Their structure is characterized using scanning electron microscopy （SEM） and Fourier transform infrared spectroscopy （FT-IR）. The imprinting site and formation mechanism is elucidated. Adsorption performance is evaluated by high performance liquid chromatography （HPLC） and liquid chromatography-mass spectrometry （LC-MS）. Selectivity and enrichment efficiency in plasma are assessed. The experiment covers material design， synthesis， and characterization. It also includes application performance evaluation. This demonstrates high-level innovation and challenge. The practice enhances students’ innovative thinking and practical skills. It fosters social and professional responsibility. The project cultivates high-quality applied pharmaceutical talents. This represents a beneficial practice in holistic education.
