Title
(EN) FUEL IDENTIFICATION WITH SURFACE ENHANCED RAMAN SPECTROSCOPY TAGS
(FR) IDENTIFICATION DE COMBUSTIBLE AVEC DES MARQUEURS DE SPECTROSCOPIE DE L'EFFET RAMAN EXALTÉ DE SURFACE
Abstract
(EN)
A method of identifying a quantity of fuel which includes the association of a substance having a known Raman spectrum with a quantity of fuel. In one embodiment, a nanoparticle including a SERS active core may be mixed into a fuel supply. In an alternative embodiment, a SERS active dye including a Raman active reporter molecule may be mixed with a quantity of fuel. If the quantity of fuel is tagged with a dye having Raman active reporter molecules, the process of identifying the quantity of fuel may include mixing into a sample of the fuel a colloid of Raman enhancing metal particles. Suitable metals include, but are not limited to, silver or gold. Alternatively, a portion of the sample may be associated with a SERS active substrate.

L'invention concerne un procédé d'identification d'une quantité de combustible comportant l'association d'une substance possédant un spectre de Raman connu avec une quantité de combustible. Dans un mode de réalisation, des nanoparticules incluant un noyau actif SERS peuvent être incorporées dans une alimentation en combustible. Dans un autre mode de réalisation, un colorant actif SERS comprenant une molécule reporter active de Raman peut être mélangé à une quantité de combustible. Si la quantité de combustible est marquée par un colorant possédant des molécules reporters actives de Raman, le procédé d'identification de la quantité de combustible peut comporter l'incorporation d'un colloïde de particules métalliques amplificatrices de Raman par mélange dans un échantillon du combustible. Les métaux appropriés incluent, mais sans y être limités, l'argent ou l'or. En variante, une partie de l'échantillon peut être associée à un substrat actif SERS.
