Molecular imprinting is a technology to create recognition sites in a macromolecular matrix using
a template molecule. The molecular imprinting technique necessitates a synthetically prepared
polymer matrix to form cavities sculpted around the template molecules of the same kind. MIPs
are easy to prepare, stable, inexpensive and capable of molecular recognition. In this study, a MIP
based carbon paste electrode (CPE) has been prepared for sarcosine determination and fully
characterized in terms of composition, usable pH range, response time. The electrode has been
applied for the potentiometric determination of sarcosine with relative standard deviations of 5.7
%. The modified electrode has been shown the lineer concentration range of 10−6 to 10−2 mmolL−1
with the limit of detection 0.70×10-6 mmolL−1 at the pH 5.0. The electrode has exhibited good
selectivity for sarcosine according to a glycine. The proposed potentiometric method has been
offered the advantages of simplicity, accuracy, automation feasibility and applicability to turbid
and colored sample solutions.
