Abstract:

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.

Key words: comprehensive pharmaceutical innovation experiment, molecularly imprinted polymers (MIPs), biological sample pretreatment, structural characterization, efficiency evaluation
