“…Hong and co-workers have reported a system involving doping MIPs with metalloporphyrins in an array to discriminate a variety of structurally similar amines. 127 These amines comprised both primary and secondary amines and amines with other functional groups including a pharmaceutical agent. The four MIPs are synthesized using three amines as templates, phenethylamine, tyramine and (+)-norephedrine as well as a non-imprinted version (Figure 14a).…”

Chemical sensors play an important role in our understanding of chemical and biological systems, providing sensitive and rapid detection of a variety of substrates. Array-based sensing approaches avoid the ongoing challenge of designing and synthesizing selective receptors for particular analytes, a labor-intensive process that can frustrate the development of sensors. Instead, cross-reactive sensor arrays utilize multiple sensing elements that interact uniquely with each analyte and produce a distinct pattern of responses, enabling identification. To date, there are a variety of strategies both to gain cross-reactivity and diversity of sensors required for array-based sensing, and to broaden the scope of analytes for detection. Sensor arrays constructed using macromolecular components, such as polymers and nanoparticles, offer an attractive route to the discrimination of multiple, similar analytes, particularly within the context of biological sensing, where recognition over large areas is often required. Here, we focus on macromolecular sensing arrays underpinned by optical detection methods, which can enable rapid, sensitive detection of a range of analytes. We discuss the current state-ofthe art and explore the challenges to be overcome in translating exciting scientific advances to applications beyond the laboratory.

“…Multichannel MIP sensor arrays have been proven to be a highly practical and effective format with good discrimination and accuracy . Their sensing strategy is similar to that of the nose or the tongue, which are able to differentiate and identify an almost unlimited number of fragrances and flavors by a finite number of different sensing cells.…”

“…For example, Liu et al reported the creation of a 2D imprinted polymer‐coated mass‐sensitive quartz crystal microbalance sensor array that can detect staphylococcus enterotoxin A and staphylococcus enterotoxin B . Previous work using a colorimetric MIP array or a 2D sensor array orthogonal combination of four MIPs and three dyes have been successful for the discrimination of amines . However, very little attention has been paid to the discrimination of various structurally similar dyes by sensors.…”

Selective recognition and discrimination of water-soluble azo dyes by a seven-channel molecularly imprinted polymer sensor array

et al. 2014

A seven-channel molecularly imprinted polymer sensor array was prepared and characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, UV-Vis spectroscopy, and nitrogen physisorption studies. The results revealed that the imprinted polymers have distinct-binding affinities from those of structurally similar azo dyes. Analysis of the UV-Vis spectral response patterns of the seven dye analytes against the imprinted polymer array suggested that the different selectivity patterns of the array were closely connected to the imprinting process. To evaluate the effectiveness of the array format, the binding of a series of analytes was individually measured for each of the seven polymers, made with different templates (including one control polymer synthesized without the use of a template). The response patterns of the array to the selected azo dyes were processed by canonical discriminant analysis. The results showed that the molecularly imprinted array was able to discriminate each analyte with 100% accuracy. Moreover, the azo dyes in two real samples, spiked chrysoidin in smoked bean curd extract and Fanta lime soda (containing tartrazine), were successfully classified by the array.
