“…Current electronic nose devices based on metal oxide semiconductors or conducting polymers that specifically identify gaseous odorants are typically large and expensive and thus not adequate for use in micro-or nano-arrays that could mimic the performance of the natural olfactory system. [1][2][3][4][5] Moreover, they are hampered by the presence of water, they do not involve molecular recognition of odorants, and they require a large sample size to ensure an optimal interaction with sensor surface. 2,4,6 Replacing these physical or chemical sensing elements with olfactory receptors (ORs) would provide a new platform with the capacity to overcome these weaknesses, resulting in bioelectronic olfaction devices.…”

We describe how mammalian olfactory receptors (ORs) could be used as sensing elements of highly specific and sensitive bioelectronic noses. An OR and an appropriate G(alpha) protein were co-expressed in Saccharomyces cerevisiae cells from which membrane nanosomes were prepared, and immobilized on a sensor chip. By Surface Plasmon Resonance, we were able to quantitatively evaluate OR stimulation by an odorant, and G protein activation. We demonstrate that ORs in nanosomes discriminate between odorant ligands and unrelated odorants, as in whole cells. This assay also provides the possibility for quantitative assessment of the coupling efficiency of the OR with different G(alpha) subunits, without the interference of the cellular transduction pathway. Our findings will be useful to develop a new generation of electronic noses for detection and discrimination of volatile compounds, particularly amenable to micro- and nano-sensor formats.

“…Two approaches can be distinguished among e-nose users: investigations conducted using the commercially available sensors [147,148] as well as construction of custom sensor arrays, like the one presented in Figure 4. The former is characterized by numerous advantages because such devices are pre-calibrated, pre-configured, and usually provided with software for data acquisition and analysis.…”

In this review, the problem of microbiological infestation of buildings was discussed. The techniques of detection were described as well, with special attention drawn to the rapid-early detection methods based on gas sensor arrays. The physical and chemical conditions of the building environment conducive to the development of microorganisms and the technical conditions influencing the problem of microbiological infestation were investigated. Additionally, the harmful effects on human health caused by the microbiological contamination were discussed, with a short review of particular groups of microorganisms causing sick building syndrome. Among the detection techniques, the traditional microbiological techniques as well as the molecular and chemical methods were presented. Different designs of the gas sensor arrays together with the various techniques of analyzing the received multidimensional signal were described, analyzed, and compared in detail.

“…In general, chemosensors function with a change in mass, or in the electrical, thermal, optical, or properties of a sensing material. The development of chemical odor sensors began in the early 1980s [Vanneste and Geise, 2003], and has progressed rapidly. Commercially available sensors are described briefly in Table 1 [Nanto andStetter, 2003, andVanneste andGeise, 2003].…”
