The goal of this work is to test the possibility of selective detection of furfural (2-FAL) in aqueous solutions, with a molecularly imprinted polymer (MIP) receptor exploiting two different transduction methods, for food safety applications. In particular, sensors with electrochemical and surface plasmon resonance (SPR) transduction are considered. Two concentration ranges could be investigated by the different sensing approaches since the detectable concentration level depends on the sensitivity of the detection technique employed. The determination of 2-FAL at different concentration levels in the aqueous medium of interest, as for example beverages, is becoming a very crucial task not only for the relevance of furanic compounds in affecting the flavor but also for their possible toxic and carcinogenic effects on the human beings. For these reasons, their determination by a fast, easy and low-cost method is of interest. The sensor methods here proposed appears to be particularly suitable, since, although together and not individually, they allow the determination in a wide concentration range.

A simple and sensitive high performance liquid chromatographic method for simultaneous determination of sulfachloropyridazine and sulfapyridine has been developed. This method was developed by using self-prepared molecularly imprinted polymers (MIPs) as the stationary phase. The polymers were prepared by a noncovalent method with sulfachloropyridazine as the template, methacrylic acid as the functional monomer and ethylene glycoldimethacrylate as the cross-linker in the presence of chloroform as the solvent. In order to compare the chromatographic data from the stationary phase, the retention time of sulfachloropyridazine and sulfapyridine was given. The separation factors (α) were 1.79–1.89 that showed that the MIPs were able to recognize sulfachloropyridazine and sulfapyridine.

A flow-injection chemiluminescence (FI-CL) sensor for metformin determination based on recognition materials of molecularly imprinted polymers (MIP) is reported. The sensor was fabricated by packing the MIP particles into a V-shape flow cell. Metformin could be selectively on-line adsorbed by the MIPs and then sensed by its great enhancing effect on the weak CL reaction between N-bromosuccinimide (NBS) and fluorescein. The CL intensity was linear to metformin concentration in the range from 2×10−8 to 8×10−6 g•mL−1 and the limit of detection (L.O.D.) was 6×10−9 g•mL−1 (3σ). The sensor showed high selectivity, improved sensitivity and excellent stability and reversibility compared with the CL method without using MIPs. The lifetime of the sensor was investigated and MIPs could be reused for more than 200 times. The sensor has been directly applied to determine metformin in human urine.

A surface plasmon resonance (SPR) platform, based on a D-shaped plastic optical fiber (POF), combined with a biomimetic receptor, i.e., a molecularly imprinted polymer (MIP), is proposed to detect 2-furaldheide (2-FAL) in fermented beverages such as wine. The determination of 2-FAL in food samples is becoming a very crucial task, on the one hand for its role in the flavor and on the other in relation to its toxic and carcinogenic effects on human beings. The proposed sensing device is easy to use and cheap; it has been tested successfully for the detection and quantification of substances of interest in different fields, such as health, the environment and industry. The possibility of performing single-drop measurements is a further favorable aspect for practical applications. As an example, the use of an SPR-MIP sensor for the analysis of 2-FAL in wine, in a concentration range useful for practical applications, is here described.
