In chapter four, molecular imprinting polymers against amino acid derivatives utilizing 2-VP+AM as combined functional monomer and trimethylolpropane trimethacrylate as tribasic cross-linker were prepared and result was compared with those with the same amino acid derivative as the imprinted molecules utilizing ethyleneglycol dimethacrylate as dibasic cross-linker. It was found that cross-link intensity of the molecular imprinting polymer is higher when TRIM was utilized and baseline separation for the imprinted molecule could be achieved. When TRIM was utilized as cross-linker more molecule is imprinted during the polymerization.
