Bio-benchmarking of electronic nose sensors. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Electronic noses, E-Noses, are instruments designed to reproduce the performance of animal noses or antennae but generally they cannot match the discriminating power of the biological original and have, therefore, been of limited utility.

A novel electronic nose for the detection and classification of pesticide residue on apples

open access: yesRSC Advances, 2021
Excessive pesticide residues are a serious problem faced by food regulatory authorities, suppliers, and consumers. To assist with this challenge, this work aimed to develop a method of detecting and classifying pesticide residue on fruit samples using an

Steady vs. Dynamic Contributions of Different Doped Conducting Polymers in the Principal Components of an Electronic Nose's Response [PDF]

open access: yesarXiv, 2023
Multivariate data analysis and machine-learning classification become popular tools to extract features without physical models for complex environments recognition. For electronic noses, time sampling over multiple sensors must be a fair compromise between a period sufficiently long to output a meaningful information pattern, and sufficiently short to

Quantification of Wine Mixtures with an Electronic Nose and a Human Panel

open access: yesFrontiers in Bioengineering and Biotechnology, 2018
In this work, an electronic nose and a human panel were used for the quantification of wines formed by binary mixtures of four white grape varieties and two varieties of red wines at different percentages (from 0 to 100% in 10% steps for the electronic ...

Wine quality rapid detection using a compact electronic nose system: application focused on spoilage thresholds by acetic acid [PDF]

open access: yesLWT, Volume 108, 2019, Pages 377-384, 2020
It is crucial for the wine industry to have methods like electronic nose systems (E-Noses) for real-time monitoring thresholds of acetic acid in wines, preventing its spoilage or determining its quality. In this paper, we prove that the portable and compact self-developed E-Nose, based on thin film semiconductor (SnO2) sensors and trained with an ...

An electronic nose using a single graphene FET and machine learning for water, methanol, and ethanol

open access: yesMicrosystems & Nanoengineering, 2020
The poor gas selectivity problem has been a long-standing issue for miniaturized chemical-resistor gas sensors. The electronic nose (e-nose) was proposed in the 1980s to tackle the selectivity issue, but it required top-down chemical functionalization ...

Application of a novel tool for diagnosing bile acid diarrhoea [PDF]

open access: yes, 2013
Bile acid diarrhoea (BAD) is a common disease that requires expensive imaging to diagnose. We have tested the efficacy of a new method to identify BAD, based on the detection of differences in volatile organic compounds (VOC) in urine headspace of BAD vs.

Kullback–Leibler Importance Estimation Procedure to Improve Gas Quantification in an Electronic Nose

open access: yesChemosensors, 2022
An electronic nose sensor array can classify and quantify different types of gases; however, the sensor can alter its measurement capability over time. The main problem presented during the measurements of the sensors is related to the variation of the ...
