A new biomimetic sensor based on molecularly imprinted polymers for highly sensitive and selective determination of hexazinone herbicide

Magnetically separable polymer (Mag-MIP) for selective analysis of biotin in food samples

“…Thus, the asymmetrical hysteresis loops with evaporation branches are steeper than the corresponding condensation branches located at high capillary condensation pressures (>0.8P 0 ). This behavior is characteristic for mesoporous materials (average diameter of pore between 2 up to 50 nm), which is consistent with data showed in Table S2 and with the corresponding to acrylate-MIPs (Marestoni et al 2015).…”

“…The results show that the surface area of Mag-MIP is 15.6 times higher than the corresponding to Mag-NIP. The increasing number of pores introduced in the imprinted polymer is due to the presence of Mag-MIP selective cavities (Marestoni et al 2015). Similarly, the surface area of MIP (without magnetic particles) is 12.9 times higher than the corresponding to NIP.…”

Electrochemical sensor for the detection of estradiol based on electropolymerized molecularly imprinted polythioaniline film with signal amplification using gold nanoparticles

“…In order to assess the rebinding of 17β-estradiol in the selective cavities, MIP films were immersed in solutions of various concentrations of 17β-estradiol for 20 min and linear sweep voltammetry (LSV) was carried out in 10 mM [Fe(CN) 6 ] −3/−4 in PBS pH = 7.2 in the range of potential between 800 mV and 350 mV vs SCE, at a scan rate of 50 mV/s. Based on the height of the obtained peak, a calibration curve was constructed upon the analysis of various concentrations of 17β-estradiol ranging from 3.6 fM to 3.6 nM.…”

“…Molecularly imprinted polymers (MIPs) have been widely applied in recent years as biomimetic receptors in the development of sensors [6][7][8]. The molecularly imprinting technique involves a polymerization process of one or more functional and crosslinking monomers in the presence of the analyte of interest, which serves as the template, in a proper solvent.…”

Molecular imprinting method for fabricating novel glucose sensor: Polyvinyl acetate electrode reinforced by MnO2/CuO loaded on graphene oxide nanoparticles

“…These recognition sites can rebind a target molecule specifically in preference to other similar molecules. Because of their selectivity, MIPs are very attracted in electrochemistry to improve the electrode response to target molecules Hu et al, 2015;Tiwari & Prasad, 2015;Toro et al, 2015). Due to advantages of chemically modified carbon paste electrodes, such as simplicity, easy fabrication, low cost, renewable surface, physical and chemical stability, they have been extensively applied in various electrochemical research, such as sensors preparation (Gholivand et al, 2015;Zaib et al, 2014).…”
