Ised monomer selection

The process of producing an ion-sensing polymer includes the following steps (i) selection and preparation of ligand monomers, (ii) synthesis of ion complexes of the monomers or linear copolymers of the complexing monomers, (iii) preparation of cross-linked copolymers with the monomeric complexes or linear copolymer complexes, (iv) the testing of the polymers for ion selectivity, (v) optimisation of polymer ionic selectivity and (vi) the use of the polymers in the construction of ion-selective electrodes (ISEs) and optical sensors. 

More recently, Wang etal. reported the electrochemical determination of tetracycline with the aid of multiwall-carbon canotube-gold nanoparticle electrodes (MWNTs-GNPs), coated with MIPs (tetracycHne template, methacyhc acid monomer, and ethylene glycol dimethacrylate crosslinker), and reported detection limits of 0.04 mg [383]. In the same year, Gai et at reported a highly-sensitive MIP ion selective electrode (MIP-ISE) for the determination of tetracycline in the range of 2.0 X 10 —1.0 X 10 M with a detection limit of 1 x 10 M [392].
