DETECTION OF VOLATILES
The present invention relates to a sensing composition for detecting a volatile organic compound in its gas phase, comprising 1) a silylated cellulose selected from the group of trialkylsilyl cellulose, triarylsilyl cellulose and alkylarylsilyl cellulose; and 2) a fluorescent dye. The detection of a...

Abstract | The present invention relates to a sensing composition for detecting a volatile organic compound in its gas phase, comprising 1) a silylated cellulose selected from the group of trialkylsilyl cellulose, triarylsilyl cellulose and alkylarylsilyl cellulose; and 2) a fluorescent dye. The detection of a volatile with this sensing composition comprises placing the sensing composition (optionally present as a layer on a support) in the vicinity of a potential source of a volatile and analyzing the sensing composition to determine whether a volatile of the potential source has reached the sensing composition. This detection can be performed in a quantitative manner by means of spectrophotometric analysis, and/or by image analysis of the sensing composition. The invention is particularly useful for application in high throughput screening.
La présente invention concerne une composition de détection pour détecter un composé organique volatil dans sa phase gazeuse, comprenant 1) une cellulose silylée sélectionnée parmi le groupe constitué d'une trialkylsilylcellulose, d'une triarylsilylcellulose et d'une alkylarylsilylcellulose ; et 2) un colorant fluorescent. La détection d'une substance volatile avec cette composition de détection consiste à placer la composition de détection (facultativement présente sous la forme d'une couche sur un support) au voisinage d'une source potentielle d'une substance volatile et analyser la composition de détection pour déterminer si une substance volatile de la source potentielle a atteint la composition de détection. La détection peut être réalisée d'une manière quantitative au moyen d'une analyse spectrophotométrique et/ou par une analyse d'image de la composition de détection. L'invention est particulièrement utile pour une application dans un criblage à haut débit. |
