“…Momol et al [ 145 ] presented corroborative evidence of e-nose efficacy using a different type of electronic nose (the e-Nose 4000) to distinguish seven species of plant pathogenic bacteria that were correctly classified with an accuracy of 95% to 100%. Good results also were obtained by Hamilton et al [ 146 ]. They used a polypyrrole sensor array system for the detection of Serpula lacrymans , a wood destroying dry rot fungus responsible for millions of dollars of damage annually to buildings containing lumber or timbers in Northern and Central Europe, Australia, and Japan.…”

Electronic-nose devices have received considerable attention in the field of sensor technology during the past twenty years, largely due to the discovery of numerous applications derived from research in diverse fields of applied sciences. Recent applications of electronic nose technologies have come through advances in sensor design, material improvements, software innovations and progress in microcircuitry design and systems integration. The invention of many new e-nose sensor types and arrays, based on different detection principles and mechanisms, is closely correlated with the expansion of new applications. Electronic noses have provided a plethora of benefits to a variety of commercial industries, including the agricultural, biomedical, cosmetics, environmental, food, manufacturing, military, pharmaceutical, regulatory, and various scientific research fields. Advances have improved product attributes, uniformity, and consistency as a result of increases in quality control capabilities afforded by electronic-nose monitoring of all phases of industrial manufacturing processes. This paper is a review of the major electronic-nose technologies, developed since this specialized field was born and became prominent in the mid 1980s, and a summarization of some of the more important and useful applications that have been of greatest benefit to man.

“…Concerning the detection module, preliminary tests from polymer sensors enabled to discriminate laboratory contaminated environments from sterile one . These findings were reinforced by other studies which discriminate different laboratory contaminated environments (Gibson, Prosser et al 1997;Canhoto, Pinzari et al 2004;Dutta, Morgan et al 2005;Hamilton, Hepher et al 2006;Bailey, Pisanelli et al 2008).…”

A new approach to detect early or hidden fungal development in indoor environments

In addition to the biodegradation problems encountered in buildings, exposure of their occupants to mold is responsible for numerous diseases such as respiratory infections, immediate or delayed allergies and different types of irritations. However, current techniques are unable to detect mold at an early stage of development or hidden contaminants. Moularat et al., in 2008 has established chemical fingerprints of moldy growth from Volatile Organic Compounds (VOCs) arising specifically from fungal metabolism and developed the Fungal Contamination Index (FCI) (Moularat et al., 2008a,b). This index has the advantage of detecting fungal development both reliably and rapidly before any visible signs of contamination could be detected. However, even though the FCI has been widely tested, VOCs' analysis by GC/MS, which is required for index calculation, is incompatible with real-time monitoring strategy for indoor environments. In this context, researches around FCI exploitation have been followed up in order to provide a monitoring device widely deployable which is the result of the miniaturization of an analytical chain for portable, reliable and low-cost applications. This device is based on one hand the selection and concentration of chemical compounds from the sample of interest and on the other hand the development of an array of different conducting polymer based sensors in order to obtain a specific footprint. This fungal contamination detection device was the subject of patent applications by the CSTB. The modularity of the system (ability to vary both the elements of detection polymers and retention time of interest) allows for expansion of its use to other pollutants.

“…An additional advantage of sensor arrays is the possibility to make analysis of poor defined analytes, such as aromas or taste of food products. Conductometric electronic noses based on CP were applied for detection of fire [132], aromatic hydrocarbons [133], bacteria and fungi [134][135][136][137][138][139][140], pollutants in water [134,141], for monitoring of emissions from sewage plants [142] or for analysis of wines [143], olive oils [144,145], different soils [146] and grain quality [147] and other poor defined analytes. Surprisingly, instead of using of different classes of CP, derivatives of one CP were typically used to get different selectivity of single sensors of the electronic noses.…”
