“…[16] MIPs are frequently prepared with acrylate and vinyl derivatives polymeric materials. [1,7,[10][11][12]14] Recently, the electrosynthesized polymers such as poly(dopamine) (PDA) and poly(o-phenylenediamine) (Po-PD) have been prepared for obtaining biomimetic recognition matrices. [17][18][19] These polymers are insulating and ultrathin, which are two important desirable features for the design of a MIP capacitive sensor.…”

A newly designed molecularly imprinted polymer (MIP) material was developed and successfully used as recognition element to fabricate a capacitive sensor for enantioselective recognition of glutamic acid (Glu). The MIP with a well‐defined structure was synthesized on a gold electrode in one step by electrochemical copolymerization of o‐phenylenediamine (o‐PD) and dopamine (DA) in the presence of template molecule Glu. The resulting MIP material was characterized with a potentiostatic frequency scan method, cyclic voltammetry, capacitance measurements, atomic force microscopy, and X‐ray photoelectron spectroscopy. The structure and recognition behaviour of the copolymer film to template molecule depended on its composition. The optimal composition was at the o‐PD to DA molar ratio of 3:2. With a potentiostatic time scan method the copolymer displayed high enantioselectivity and sensitivity to the stereoselective rebinding of L‐ or D‐Glu to their corresponding artificial receptor due to the exact definition of the imprint cavity. The capacitance response of the sensor for L‐Glu or D‐Glu was proportional to their concentration in the range of 16.7 to 250 μM. The enantiometric selectivity coefficients for L‐Glu and D‐Glu imprinted films against their respective enantiomers are 24 and 15, respectively. The resulting MIP capacitive sensors showed good reproducibility, stability and repeatability. This strategy opened a convenient way for preparation of enantioselective MIPs and recognition of enantiotropic molecules.

“…Earlier, Dickert's group contributed significantly on the design and development of MIPs for viruses and other microorganisms (Dickert et al, 2004;Hayden et al, 2006;Jenik et al, 2009;Schirhagal et al, 2010). Human rhino virus 14 imprinted MIP nanoparticles formulated with poly(vinylpyrrolidone-co-methacrylic acid) and cross-linked with N,N'-(1,2-dihydroxyethylene)-bisacrylamide (DHEBA) was immobilized on a 10 MHz quartz crystal microbalance (QCM) and these pronounced good sensor responses.…”

Taking into account the lower limit of detection, the fluorescence sensing reported here is reliable, simple to perform, rapid, cost-effective and offers a sensitive analytical method for virus detection in water resources.2
