“…Until now, the most widely applied technique for the synthesis of chemical sensors based on molecularly imprinted polymers has been the noncovalent approach developed by the Mosbach group [18]. However, in recent years electropolymerization [19,24] has been an important alternative to radical polymerization for the development of MIP based sensors as it allows the monitorization and regulation of the density and the thickness of the polymeric film through the adjustment of the different polymerization conditions such as the number of cyclic scans or the voltage as well as being a fast technique, of low cost and relatively easy to work with. New transduction elements began to be employed such as quartz crystal microbalance [3], acoustic wave [4,20] or voltammetry that was employed for the first time by the Barrio group in combination with an MIP based microsensor synthesized by electrocopolymerization [15].…”

A molecularly imprinted polymer microsensor was synthesized onto the surface of a carbon fiber microelectrode (CFME) by cyclic voltammetry between À 0.1 V and þ 1.35 V at a scan rate of 50 mV s À1 . The monomers aniline and o-phenylenediamine (o-PD) were electrocopolymerized in the presence of the template (metamitron) in an aqueous medium of 0.1 M H 2 SO 4 . In order to obtain a sensor with the highest number of imprinted sites as possible, different experiments related to the polymerization process were carried out. The response of the synthesized microsensor was linear to the metamitron in the range between 10 À6 and 10 À4 with sensitivity of 0.143 nA mM À1 with good repeatability (< 9% RSD). Employing these experimental conditions, the microsensor was able to distinguish the metamitron from other closely related triazines like metribuzin or isomethiozin.

“…Different types of monomers have been studied such as polypyrrole [21], overoxidized polypyrrole [22], polyphenol [23], protoporphyrine IX [24] and poly(o-phenylenediamine) [3] that can be easily oxidized from the aqueous solutions of their monomers. The growth of these types of monomers depends on the nature of the synthesized polymer.…”

This work describes a novel use for the polymeric film, poly(o-aminophenol) (PAP) that was made respon-sive to a specific protein. This was achieved through templated electropolymerization of aminophenol (AP) in the presence of protein. The procedure involved adsorbing prot ein on the electrode surface and thereafter electroploymerizing the aminophenol. Proteins embedded at the outer surface of the polymeric film were digested by proteinase K and then washed away thereby creating vacant sites. The capacity of the template film to specifically rebind protein was tested with myoglobin (Myo), a cardiac biomarker for ischemia. The films acted as biomimetic artificial antibodies and were produced on a gold (Au) screen printed electrode (SPE), as a step towards disposable sensors to enable point-of-care applications.Raman spectroscopy was used to follow the surface modification of the Au-SPE. The ability of the mate-rial to rebind Myo was measured by electrochemical techniques, namely electrochemical impedance spectroscopy (EIS) and square wave voltammetry (SWV). The d evices displayed linear responses to Myo in EIS and SWV assays down to 4.0 and 3.5 µg/mL, respectively, with detection limits of 1.5 and 0.8 µg/mL. Good selectivity was observed in the presence of troponin T (TnT) and creatine kinase (CKMB) in SWV assays, and accurate results were obtained in applications to spiked serum. The sensor described in this work is a potential tool for screening Myo in point-of-care due to the simplicity of fabrication, disposability, short time response, low cost, good sensitivit y and selectivity.
