Title (EN) PLASTIC SURFACES AND APPARATUSES FOR REDUCED ADSORPTION OF SOLUTES AND METHODS OF PREPARING THE SAME
(FR) SURFACES PLASTIQUES ET APPAREILS PERMETTANT DE REDUIRE L'ADSORPTION DE SOLUTES ET PROCEDES DE PREPARATIONS CORRESPONDANTS
Abstract: front page image
(EN)A method of treating a plastic surface with fluorine gas to decrease adsorption of hydrophobic solute molecules to the surface is provided. The method can include treating a surface with a first gas comprising fluorine gas and a second gas comprising oxygen gas, water vapor, or both oxygen gas and water vapor. Plastics treated using the method provide useful drug discovery and biochemical tools for the testing, handling, and storage of solutions containing low concentrations of hydrophobic solutes. Microfluidic devices containing treated plastic interior surfaces and methods of using such devices to make concentration-dependent measurements are also described.
(FR)L'invention concerne un procédé permettant de traiter une surface plastique à l'aide d'un fluor gazeux afin de réduire l'adsorption de molécules de solutés hydrophobes sur la surface. Le procédé peut consister à traiter une surface à l'aide d'un premier gaz comprenant un fluor gazeux et d'un second gaz comprenant de l'oxygène gazeux, de la vapeur d'eau ou les deux à la fois. Les plastiques ainsi traités donnent des outils de recherche de médicaments et des outils biochimiques utiles et peuvent être utilisés dans l'essai, la manipulation et le stockage de solutions contenant des faibles concentrations de solutés hydrophobes. L'invention concerne également des dispositifs microfluidiques contenant des surfaces intérieures plastiques ainsi traitées et des procédés d'utilisation de ces dispositifs afin d'effectuer des mesures dépendant de la concentration.
