  • A methodology for the characterization of portable sensors for air quality measure with the goal of deployment in citizen science
    Science of the Total Environment, 2020
    Co-Authors: Baptiste Languille, Cecile Honore, Christophe Debert, Laurent Gauvin, Salim Srairi, Valerie Gros, Clement Pommier, Nicolas Bonnaire, Isabella Annesi-maesano, Basile Chaix
    Abstract:

    The field of small air quality sensors is of growing interest within the scientific community, especially because this new technology is liable to improve air Pollutant Monitoring as well as be used for personal exposure quantification. Amongst the myriad existing devices, the performances are highly variable; this is why the sensors must be rigorously assessed before deployment, according to the intended use. This study is included in the Polluscope project; its purpose is to quantify personal exposure to air Pollutants by using portable sensors. This paper designs and applies a methodology for the evaluation of portable air quality sensors to eight devices measuring PM, BC, NO2 and O3. The dedicated testing protocol includes static ambient air measurements compared with reference instruments, controlled chamber and mobility tests, as well as reproducibility evaluation. Three sensors (AE51, Cairclip and Canarin) were retained to be used for the field campaigns. The reliability of their performances were robustly quantified by

Three sensors (AE51, Cairclip and Canarin) were retained to be used for the field campaigns. The reliability of their performances were robustly quantified by using several metrics. These three devices (for a total of 36 units) were deployed to be worn by volunteers for a week. The results show the ability of sensors to discriminate between different environments (i.e., cooking, commuting or in an office). This work demonstrates, first, the ability of the three selected sensors to deliver data reliable enough to enable personal exposure estimations, and second, the robustness of this testing methodology.

  • flexible and adhesive surface enhance raman scattering active tape for rapid detection of pesticide residues in fruits and vegetables
    Analytical Chemistry, 2016
    Co-Authors: Jiaming Chen, Youju Huang, Palanisamy Kannan, Lei Zhang, Jiawei Zhang, Tao Chen
    Abstract:

    The efficient extraction of targets from complex surfaces is vital for technological applications ranging from environmental Pollutant Monitoring to analysis of explosive traces and pesticide residues. In our present study, we proposed a proof-of-concept surface enhance Raman scattering (SERS) active substrate serving directly to the rapid extraction and detection of target molecules. The novel substrate was constructed by decorating the commercial tape with colloidal gold nanoparticles (Au NPs), which simultaneously provides SERS activity and “sticky” of adhesive. The utility of SERS tape was demonstrated by directly extracting pesticide residues in fruits and vegetables via a simple and viable “paste and peel off” approach. The obtained strong and easily distinguishable SERS signals allow us to detect various pesticide residues such as parathion-methyl, thiram, and chlorpyrifos in the real samples with complex surfaces including green vegetable, cucumber, orange, and apple.
