J Pharm Biomed Anal. 2023 May 10:228:115343. doi: 10.1016/j.jpba.2023.115343. Epub 2023 Mar 14.

Abstract

The appearance of the biomarkers in body fluids like blood, urine, saliva, tears, etc. can be used for the identification of many diseases. This article aimed to summarize the studies about electrochemical biosensors with molecularly imprinted polymers as sensitive and selective layers on the electrode to detect protein-based biomarkers of such neurodegenerative diseases as Alzheimer's disease, Parkinson's disease, and stress. The main attention in this article is focused on the detection methods of amyloid-β oligomers and p-Tau which are representative biomarkers for Alzheimer's disease, α-synuclein as the biomarker of Parkinson's disease, and α-amylase and lysozyme as the biomarkers of stress using molecular imprinting technology. The research methods, the application of different electrodes, the influence of the polymers, and the established detection limits are reviewed and compared.

Keywords: Alzheimer’s disease biomarker; Electrochemical biosensor; Molecularly imprinted polymer (MIP); Parkinson’s disease biomarker.
