This study was conducted on three polycyclic aromatic hydrocarbons (PAHs): benzo[a]pyrene (BaP), fluoranthene (FL), and naphthalene (NAP). SERS substrates were chemically functionalized using 4-dodecyl benzenediazonium-tetrafluoroborate and SERS analyses were conducted to detect the pollutants alone and in mixtures. Compounds were first measured in water-methanol (9:1 volume ratio) samples. Investigation on solutions containing concentrations ranging from 10\u22126 g L\u22121 to 10\u22123 g L\u22121 provided data to plot calibration curves and to determine the performance of the sensor. The calculated limit of detection (LOD) was 0.026 mg L\u22121 (10\u22127 mol L\u22121) for BaP, 0.064 mg L\u22121 (3.2 \u00d7 10\u22127 mol L\u22121) for FL, and 3.94 mg L\u22121 (3.1 \u00d7 10\u22125 mol L\u22121) for NAP, respectively. The correlation between the calculated LOD values and the octanol-water partition coefficient (Kow) of the investigated PAHs suggests that the developed nanosensor is particularly suitable for detecting highly non-polar PAH compounds. Measurements conducted on a mixture of the three analytes (i) demonstrated the ability of the developed technology to detect and identify the three analytes in the mixture; (ii) provided the exact quantitation of pollutants in a mixture. Moreover, we optimized the surface regeneration step for the nanosensor.<\/jats:p>","DOI":"10.3390\/s17061198","type":"journal-article","created":{"date-parts":[[2017,5,24]],"date-time":"2017-05-24T07:29:42Z","timestamp":1495610982000},"page":"1198","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Diazonium Salt-Based Surface-Enhanced Raman Spectroscopy Nanosensor: Detection and Quantitation of Aromatic Hydrocarbons in Water Samples"],"prefix":"10.3390","volume":"17","author":[{"given":"Inga","family":"Tijunelyte","sequence":"first","affiliation":[{"name":"CSPBAT Laboratory, UMR 7244, UFR SMBH, University of Paris 13, Sorbonne Paris Cite, 93017 Bobigny, France"}]},{"given":"St\u00e9phanie","family":"Betelu","sequence":"additional","affiliation":[{"name":"BRGM, F-45060 Orl\u00e9ans CEDEX 02, France"}]},{"given":"Jonathan","family":"Moreau","sequence":"additional","affiliation":[{"name":"IFREMER, Brittany Center, Detection, Sensors and Measurements Laboratory, CS10070, 29280 Plouzan\u00e9, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5753-7376","authenticated-orcid":false,"given":"Ioannis","family":"Ignatiadis","sequence":"additional","affiliation":[{"name":"BRGM, F-45060 Orl\u00e9ans CEDEX 02, France"}]},{"given":"Catherine","family":"Berho","sequence":"additional","affiliation":[{"name":"BRGM, F-45060 Orl\u00e9ans CEDEX 02, France"}]},{"given":"Nathalie","family":"Lidgi-Guigui","sequence":"additional","affiliation":[{"name":"CSPBAT Laboratory, UMR 7244, UFR SMBH, University of Paris 13, Sorbonne Paris Cite, 93017 Bobigny, France"}]},{"given":"Erwann","family":"Gu\u00e9nin","sequence":"additional","affiliation":[{"name":"Laboratoire TIMR, EA4297, Sorbonne Universit\u00e9s\u2014Universit\u00e9 de Technologie de Compi\u00e8gne, Centre de recherche de Royallieu, rue du docteur Schweitzer, CS 60319, 60203 Compi\u00e8gne CEDEX, France"}]},{"given":"Catalina","family":"David","sequence":"additional","affiliation":[{"name":"HORIBA Jobin Yvon SAS, 59650 Villeneuve d\u2019Ascq, France"}]},{"given":"S\u00e9bastien","family":"Vergnole","sequence":"additional","affiliation":[{"name":"HORIBA Jobin Yvon SAS, 59650 Villeneuve d\u2019Ascq, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1524-5505","authenticated-orcid":false,"given":"Emmanuel","family":"Rinnert","sequence":"additional","affiliation":[{"name":"IFREMER, Brittany Center, Detection, Sensors and Measurements Laboratory, CS10070, 29280 Plouzan\u00e9, France"}]},{"given":"Marc","family":"Lamy de la Chapelle","sequence":"additional","affiliation":[{"name":"CSPBAT Laboratory, UMR 7244, UFR SMBH, University of Paris 13, Sorbonne Paris Cite, 93017 Bobigny, France"}]}],"member":"1968","published-online":{"date-parts":[[2017,5,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1351","DOI":"10.1039\/c1ay05038a","article-title":"Functionalized nanoporous track-etched \u03b2-pvdf membrane electrodes for lead (ii) determination by square wave anodic stripping voltammetry","volume":"3","author":"Bessbousse","year":"2011","journal-title":"Anal.
