“…The molecularly imprinted polymeric materials can recognize target molecules with the shape-complementary cavities, and their applications in the recognition of biological compounds, drugs, and agrochemicals have been studied. [4][5][6][7] The polymers such as polyacrylate, polystyrene, and polysilane include one of the most frequently used recognition matrices. 8 The great potentiality of conducting polymers toward a number of applications, such as batteries, 9 sensors [10][11][12] and ionselective electrodes, 13,14 has attracted much attention.…”

We aimed to develop a 6-chloro-N,N-diethyl-1,3,5-triazine-2,4-diamine (CAT)-sensing system based on a biomimetic receptor of a molecularly imprinted polymer for CAT and electrochemical determination of CAT. A molecularly imprinted polymer for CAT was prepared by the polymerization of methacrylic acid (MAA) as a functional monomer and ethylene glycol dimethacrylate (EDMA) as a cross-linker with a template molecule (CAT) in dimethyl formamide (DMF). The polymer prepared with the ratio of these monomers (CAT:MAA:EDMA = 1:7.5:20) showed the most selective rebinding to CAT, and the obtained polymer was recognized as a CAT-imprinted polymer (CAT-MIP). The effect of the specific imprinting sites of CAT-MIP was demonstrated by Scatchard analysis. In an aqueous solution of CAT, CAT-MIP showed the maximum binding of CAT in a 0.05 M phosphate buffer (PB), pH 5.0. The binding amount of CAT to CAT-MIP was 24% more than atrazine and 72% more than propazine. The CAT-sensing system was composed of a column of CAT-MIP particles and a voltammetry analyzer. The reductive current of CAT depended on the concentration of CAT up to 30 μM with the system.

Uniform-sized molecularly imprinted polymer (MIP) beads were prepared using a one-step swelling and polymerization method. The obtained sulfamethazine (SMZ)-imprinted polymer showed high affinity and selectivity toward SMZ and other structurally related sulfonamides in acetonitrile or water-acetonitrile mobile phases, particularly in high aqueous systems. The column performance of the MIPs for SMZ and its analogues could be improved by elevating the column temperature and optimizing the flow rate. The hydrogen-bonding effect plays a significant role in the recognition process of SMZ-imprinted polymer systems in organic media, while the ion-exchange effect, as well as hydrophobic effect, dominantes the retention mechanism in aqueous-rich media, in addition to shape recognition.
