“…About a decade ago, the electronic nose was introduced as a very rapid tool for aroma profile analysis in several fields, including medical diagnosis [9], environmental pollution monitoring [10,11], cosmetics [12], and the automotive industry [13]. More recently, it has become more popular as a nondestructive technique for food analysis.…”

An electronic nose was successfully used to detect and discriminate lard from other types of animal body fats and samples containing lard. The results are presented in the form of VaporPrint TM , the image of the polar plot of the odor amplitudes from the surface acoustic wave (SAW) detector frequency. In the VaporPrint TM , the radial angles representing the sensor provides individual fingerprints of the aroma of different animal body fats. Principal component analysis (PCA) was used to interpret the data and it provided a good grouping of samples, with 61% of the variation accounted for by PC 1 and 29% accounted for by PC 2. All of the lard-containing samples formed a separate group from the samples that were free from lard. This method can be developed into a rapid method for detecting the presence of lard in food samples for Halal authentication.

“…A wide variety of materials including polymers, ferroelectric ceramics, piezoelectric semiconductors and shape memory films have been studied and used to manufacture an assortment of chemical sensors [1][2][3]. These sensors have been used in a wide variety of applications such as gas detection, food processing, cosmetics and pharmaceuticals [4][5][6][7][8]. In recent years, textiles have also been considered as a possible avenue for developing personal sensing and monitoring systems for medical, health & safety and military applications [9][10][11].…”

Wearable sensors for monitoring and clinical applications for non-hospital-based healthcare has the potential to significantly reduce healthcare costs and permit individuals to maintain an independent lifestyle free of the constraints imposed by hospital-based care. Wearable, small chemical sensors have the potential to deliver a wide range of reliable on body monitoring systems for personal monitoring and detecting chemicals in the environment. The present work investigates the potential of using widely available commercial fabric materials as chemical sensors. Various fabrics including natural, synthetics and blends of both natural and synthetic were treated with gold nanoparticle solutions to determine the treatments effectiveness in changing a materials electrical resistance. The studies found treating the fabrics reduced the materials resistive characteristics. The study also found that treated natural silk fabrics could also be used to detect ethanol vapour. Thus, making treated silk fabrics a potential chemical sensor.

A specially designed electronic nose was coupled to an air-lift bioreactor in order to perform on-line monitoring of released vapors. The sensor array was placed at the top of the bioreactor sensing the headspace in equilibrium with the evolving liquor at any time without the need of aspiration and pumping of gases into a separated sensor chamber. The device was applied to follow the off-gas of a bioreactor with Acidithiobacillus thiooxidans grown on beds of elemental sulfur under aerobic conditions. Evolution was monitored by acid titration, pH and optical density measurements. The electronic nose was capable to differentiate each day of reactor evolution since inoculation within periods marked off culture medium replacements using multivariate data analysis. Excellent discrimination was obtained indicating the potentiality for on-line monitoring in non-perturbed bioreactors. The prospects for electronic nose/bioreactor merging are valuable for whatever the bacterial strain or consortium used in terms of scent markers to monitor biochemical processes.
