Title (EN) A CARBON NANOTUBE-HYDROGEN PEROXIDE HYBRID BASED OPTICAL SENSING METHOD FOR ASSESSMENT OF ANTIOXIDANT POTENCY
(FR) PROCÉDÉ DE DÉTECTION OPTIQUE À BASE D'UN HYBRIDE NANOTUBES DE CARBONE-PEROXYDE D'HYDROGÈNE POUR L'ÉVALUATION D'UN POUVOIR ANTIOXYDANT
Abstract: front page image
(EN)An ultrasensitive dual optical method for measuring antioxidant concentration and total antioxidant capacity is provided. Using the process, the detection limit for vitamin C is as low as 7 nM. The method is based on a hybrid of single walled carbon nanotubes (SWNT) with hydrogen-peroxide. The method provides is a robust, cheap, fast, and reusable optical sensing method for antioxidant and total antioxidant capacity measurement in foods and plasma. The method can also be developed as a miniature assay for both in vitro and in vivo detection.
(FR)L'invention porte sur un procédé optique double ultrasensible pour mesurer la concentration en antioxydant et la capacité anti-oxydante totale. En utilisant le procédé, la limite de détection pour la vitamine C est aussi faible que 7 nM. Le procédé est basé sur un hybride de nanotubes de carbone à simple paroi (SWNT) avec le peroxyde d'hydrogène. Le procédé fournit un procédé de détection optique robuste, bon marché, rapide et réutilisable pour la mesure de la teneur en antioxydant et de la capacité antioxydante totale dans les aliments et le plasma. Le procédé peut également être développé en tant qu'essai miniature pour la détection à la fois in vitro et in vivo.
