Abstract: A novel method characterized by high sensitivity, low cost and high stability was developed. This method based on a molecularly imprinted polymer(MIP) using a functional monomer which is trimethoxysiane(TMS) and itaconic acid (ITC), suitable cross-linker and the template which is Metoclopramide(MTPD) to fabricate a monolithic solid-phase micro extraction (SPME) fiber. A polymer was The molecularly imprinted fiber and the molecularly non-imprinted membranes were synthesized without selective binding sites this was referred to as a non-imprinted polymer (NIP). The new synthesis electrodes were successfully used for the analyte estimated in preparation pharmaceutical sample without any time consuming pretreatment steps. Monitoring of the analytes was performed using UV-vis and Scanning electron microscopy (SEM) and FTIR. The relative standard deviations ( RSD%) for five Patients repeated experiments for three measurements is (2.48-3.26) %. The relative recoveries obtained for MTPD in spiked human urine samples are in the range of (94.83-98.36).
