“…BaP at the highest tested concentration (10 M) leads to a loss of signal by approximately fifty eight percent. The detection limit (S/B = 3) is estimated to be 10 nM (equal to 2.4 ng mL −1 ), which is 10-fold lower than the result obtained in a previous work by competitive inhibition voltammetric immunoassay (Liu et al, 2000), and is as sensitive as the enzyme-labeled amperometric immunoassay for phenanthrene (Fahnrich et al, 2003). The detection limit for BaP varies in other established immunoassays.…”

“…ECIA has attracted great attention for the on-site screening of environmental pollutants due to its advantages of short response time, low-cost, small size and adequate sensitivity (Liu et al, 1998(Liu et al, , 2000Fahnrich et al, 2003;Moore et al, 2004;Badihi-Mossberg et al, 2007;Lin et al, 2007). In particular, miniaturization of electrochemical devices can be achieved by employing well-established microelectronics fabrication techniques.…”

“…Polycyclic aromatic hydrocarbons that are present in nonprocessed foodstuffs are associated with environmental pollution from both human and industrial activities. [33] An amperometric biosensor for detecting PAHs was developed by Fahnrich [34]. The coating screen-printed carbon electrode antigen is phenanthrene-9-carboxaldehyde coupled to bovine serum albumin (BSA).…”

This article reviews recent advances in electrochemical biosensing and detection of environmental pollutants. Electrochemical biosensors offer precision, sensitivity, rapidity, and ease of operation for on-site environmental analysis. An electrochemical biosensor is an analytical device in which a specific biological recognition element (bioreceptor) is integrated within or intimately associated with an electrode (transducer) that converts the recognition event to a measurable electrical signal for the purpose of detecting a target compound (analyte) in solution. This approach not only provides the means for on-site analysis but also removes the time delay and sample alteration that can occur during transport to a centralized laboratory. We first address the basic principles of merging of electrochemistry and biology into a biosensing system, and then we discuss various environmental monitoring strategies involving this technology.

“…Fähnrich et al (2003) developed an amperometric immunosensor for phenanthrene detection at 300 mV with the alkaline phosphatase enzyme and a detection limit of 800 parts-per-trillion (ppt). Gobi and Miura (2004) have reported the detection of benzo(a)pyrene (BaP) with immunosensor chips working by an indirect competitive immunoreaction method and it allows the detection of BaP at a concentration as low as 10 ppt with a response time of 15 min.…”

Résumé -Biocapteurs pour l'environnement -La présence de polluants d'origine industrielle ou agricole dans l'environnement, et dans les eaux en particulier, est liée à l'utilisation massive de composés tels que les herbicides et pesticides, les solvants chlorés ainsi que les composés des essences qui peuvent être déversés lors du transport et du stockage des carburants. Les composés chimiques concernés sont généralement toxiques pour l'homme et les animaux. Cette toxicité nécessite dans les cas de pollution de suivre l'évolution de ces composés (en particulier en cas de menace sur des captages d'eau potable). Les outils classiques de mesure (CPG, CPG/SM, etc.) sont très efficaces du point de vue de la sensibilité et de la reproductibilité mais leur utilisation nécessite d'effectuer des prélèvements sur site, de transporter les échantillons puis de les analyser au laboratoire. Les délais induits peuvent être rédhibitoires et les coûts ne sont pas négligeables quand de nombreux échantillons sont à analyser sur des périodes de temps longues. C'est pour ces raisons que de nouveaux appareils de mesure, biosenseurs ou biocapteurs, qui profitent de l'avancée des connaissances dans plusieurs domaines scientifiques et dans celui de la biologie en particulier, ont été conçus. Ils permettent la création d'outils analytiques aussi fiables mais plus sélectifs et peu encombrants, qui fournissent des mesures en temps réel sur le site étudié.
