Health Canada requires the food industry to declare 10 allergens and gluten sources on food packaging. Given the growing number of tests required, and the high cost of allergen detection methods such as ELISA (Enzyme-Linked Immuno-Sorbent Assay), the famous precautionary statement \u00ab\u00a0May contain …\u00a0\u00bb has become overspread. In the absence of a more effective and less costly detection method, allergy sufferers will continue to impose either a restrictive diet or a risk to their health.<\/span><\/p>\n A team of researchers from three Quebec universities (Universit\u00e9 de Sherbrooke, UdeS, Universit\u00e9 de Montr\u00e9al, UdeM and Universit\u00e9 Laval) has teamed up with two government agencies (Canadian Food Inspection Agency, Health Canada) and two non-profit consumer <\/span>organizations (Food Allergy Canada and C\u0153liaque Qu\u00e9bec) to develop a new allergen detection method that is more robust, more sensitive, and less expensive than ELISA. The mehtod is based on a Raman probe, which consists of a carbon nanohorn (CNH) in which <\/span>a dye is encapsulated and onto which an antibody is grafted. The Raman signal will be more precise and detailed than the fluorescence signal from ELISA and will enable parallel acquisition of signals from more than one allergen at a time. The aim is to offer the agri-food <\/span>industry an effective, robust and less expensive device. Ultimately, this technological leverage will enable stakeholders to improve the use of precautionary allergen labelling and better protect allergic consumers.<\/span><\/p>\n The aim of this proposed thesis project<\/strong> is to optimize the plasma synthesis of CNHs, focusing on dye purification and encapsulation. The candidate will (i) optimize the CNHs nanostructure, (ii) refine the dye purification and encapsulation protocols (iii) identify the <\/span>dyes to be encapsulated in CNHs based on the distinctive aspects of their Raman spectra (iv) characterize the probes by transmission electron microscopy to better understand the interaction between the dyes and the CNHs. This work will help clarify the mechanisms <\/span>by which CNHs are encapsulated, to improve the R-ELISA probe and establish a solid basis for the selection and encapsulation protocol.<\/span><\/p>\n This thesis will be supervised by Prof. Nadi Braidy of UdeS and Prof. Richard Martel of UdeM. Most of the work will be carried out at the UdeS’s Institut interdisciplinaire d’innovation technologique (3IT), notably in the new transmission electron microscopy <\/span>laboratory, with internships planned in UdeM laboratories. The project will be carried out in close collaboration with Universit\u00e9 Laval, project partners and collaborators in international laboratories. The candidate will thus benefit from an exceptional international research environment where students, engineers, professors and industrialists work hand in hand to develop the technologies of the future to improve public health and the food industry in Canada.<\/span><\/p>\n <\/p>\n – University degree and master’s degree in engineering or science in chemistry, materials or physics.<\/span><\/p>\n – Experience in synthesis or characterization of carbon nanomaterials.
