Title : Molecularly imprinted polymers electrochemical sensors: Form macro to micro molecules detection

Abstract:

Molecularly imprinted polymers (MIPs) are synthetic materials with so many applications as recognition elements in many types of electrochemical sensors due to their very unique properties including: high thermal stability, longer shelf stability, reusability besides higher selectivity that is comparable to natural biological receptors. 
For a chemical sensor to work, two mechanisms are required: recognition and transduction. MIPs play a wonderful role as recognition receptors in combination with a transducer that transforms the concentration of substrate or the product of interaction of the target material in the electrode matrix into electrical signal that is amplified and further processed
Molecularly imprinted polymers (MIPs) can be easily Incorporated either on polymeric membrane or within solid matrix to form the active electrode surface allowing the design of electrochemical sensors with very fixable analytical characteristics .Also, Magnetic Molecularly imprinted polymers (MMIP) can be utilized to improve properties of the sensor by offering a simple and fast elution of the template molecules from MMIPs by simply using an external magnetic field. 
Many other materials were also combined with MIP to give electrodes of improved analytical performance to fit in different applications, such as nanomaterials such as gold and silver nanoparticles (AuNPs and AgNPs), single-walled and multi walled carbon nanotubes (SWCNTs and MWCNTs). Also, different types of MIPs were applied including, bulk, surface imprinted, hydrogels.
The recent advances in application of MIP as recognition receptors will be discussed in this presentation.
