A CHEMICAL BIOCHEMICAL OR BIOLOGICAL ANALYSIS SYSTEM UTLIZING LUMINESCENT DETECTION

摘要

A chemical, biochemical or biological analysis system and method including: a surface acoustic wave (SAW) actuator (6) including a piezoelectric substrate (9) and at least one interdigital electrode (17) located on a working surface (11) of the piezoelectric substrate (9), the SAW actuator generating travelling SAWs in the working surface when an electrical signal is applied to the interdigital electrode; at least one reaction chamber (19) located on the working surface of the piezoelectric substrate; a light detector (16) for detecting luminescent, fluorescent or phosphorescent emissions within the reaction chamber; a reagent flow line (29) for providing a flow of reagent through the reaction chamber; a test sample supply line (29) for supplying a test sample to the reaction chamber; wherein the SAW actuator can generate travelling SAWs within the working surface to thereby induce chaotic micromixing, convective transport, concentration or combinations thereof of the test sample and the reagent contained within the reaction chamber.
