Abstract[English]
A method including providing a test system, applying a water sample to the test system, and determining a concentration of a pollutant in the water sample using surface-enhanced Raman spectroscopy of the test system. The test system may include a silicon nanofiber film, a plurality of ZnO nanorods arranged in an array on the silicon nanofiber film, and a plurality of particles disposed on the plurality of ZnO nanorods. The plurality of ZnO nanorods have a top surface and a side surface, and the side surface is arranged between the top surface and the silicon nanofiber film.[French]
L'invention concerne un procédé comprenant la fourniture d'un système de test, l'application d'un échantillon d'eau au système de test, et la détermination d'une concentration d'un polluant dans l'échantillon d'eau à l'aide d'une spectroscopie Raman exaltée de surface du système de test. Le système de test peut comprendre un film de nanofibres de silicium, une pluralité de nanotiges de ZnO agencées en réseau sur le film de nanofibres de silicium, et une pluralité de particules disposées sur la pluralité de nanotiges de ZnO. La pluralité de nanotiges de ZnO ont une surface supérieure et une surface latérale, et la surface latérale est agencée entre la surface supérieure et le film de nanofibres de silicium.
