Molecularly imprinted polymers (MIPs) based electrochemical sensors for the determination of catecholamine neurotransmitters – Review

Abstract

Abstract Molecularly imprinted polymers (MIPs) have been widely used for the modification of electrodes because of their native specificity for the intrinsic template molecules. The importance of catecholamines in the neurological and general well‐being of every individual cannot be overemphasized. Disorders associated with the imbalance in catecholamine levels can be diagnosed with electrochemical sensors capable of their determination in the presence of other biological interferents in extracellular fluids. MIPs based sensors have been designed for selective and simultaneous determination of these catecholamines in the past decade. Efforts in this regard and details on the components and preparation of these MIPs were presented in this review.
