“…For SPR determination of T-2 toxin (T-2), an MIPAPBA film was in situ deposited on an SPR chip by potentiodynamic electropolymerization of APBA, in the presence of T-2 [113]. Next, the template was removed by washing first with 80% methanol and then with PBS (pH = 7.4) which was 0.05% in Tween 20.…”

“…The studies described above concluded that the boronic acid based functional monomers can generate complexes of MIPs and analytes with high stability constants [113], comparable to those of enzyme- or antibody-based biorecognition systems. However, in most studies, these stability constants were not reported (Table 2).…”

This critical review describes a class of polymers prepared by electrochemical polymerization that employs the concept of molecular imprinting for chemical sensing. The principal focus is on both conducting and nonconducting polymers prepared by electropolymerization of electroactive functional monomers, such as pristine and derivatized pyrrole, aminophenylboronic acid, thiophene, porphyrin, aniline, phenylenediamine, phenol, and thiophenol. A critical evaluation of the literature on electrosynthesized molecularly imprinted polymers (MIPs) applied as recognition elements of chemical sensors is presented. The aim of this review is to highlight recent achievements in analytical applications of these MIPs, including present strategies of determination of different analytes as well as identification and solutions for problems encountered.

“…Moreover, the quenching of a covalently embedded dye, lacking designated receptor sites, can only be employed for analytes which are potent quenchers. [9] The perhaps most obvious approach, the covalent integration of a fluorescent probe monomer into a MIP, however has only seldom been accomplished, [10][11][12][13][14] and especially examples showing directional recognition at a designated binding site [12][13][14] or fluorescence enhancement upon analyte binding are rare. [13] The most appealing type, fluorogenic MIPs that simply "light up" in an analytically useful wavelength range upon binding of the analyte have, to our knowledge, not been reported.…”

“…Gupta and coworkers proposed the electropolymerization of 3-aminophenylboronic acid (3-APBA) to nanopattern the SPR optical structure with cavities for the recognition of the T-2 toxin (T-2). Results showed that the MIP sensor exhibited a linear response for T-2 from 2.1 fM to 33.6 fM and had an LoD of 0.1 fM (0.05 pg/mL) [ 75 ]. Lately, Baldoneschi and coworkers demonstrated the use of norepinephrine as a new monomer for MIP electropolymerization [ 76 ].…”

Optical sensing, taking advantage of the variety of available optical structures, is a rapidly expanding area. Over recent years, whispering gallery mode resonators, photonic crystals, optical waveguides, optical fibers and surface plasmon resonance have been exploited to devise different optical sensing configurations. In the present review, we report on the state of the art of optical sensing devices based on the aforementioned optical structures and on synthetic receptors prepared by means of the molecular imprinting technology. Molecularly imprinted polymers (MIPs) are polymeric receptors, cheap and robust, with high affinity and selectivity, prepared by a template assisted synthesis. The state of the art of the MIP functionalized optical structures is critically discussed, highlighting the key progresses that enabled the achievement of improved sensing performances, the merits and the limits both in MIP synthetic strategies and in MIP coupling.
