Zusammenfassung |

[EN] The invention relates to a method, a kit and a device for controlling the flux of penetrants across an adaptable semi-permeable porous barrier, the method comprising the steps of: preparing a formulation by suspending or dispersing said penetrants in a polar liquid in the form of fluid droplets surrounded by a membrane-like coating of one or several layers, said coating comprising at least two kinds of forms of amphiphilic substances with a tendency to aggregate, said penetrants being able to transport agents through the pores of said barrier or to enable agent permeation through the pores of said barrier after penetrants have entered the pores, selecting a dose amount of said penetrants to be applied on a predetermined area of said barrier to control the flux of said penetrants across said barrier, and applying the selected dose amount of said formulation containing said penetrants onto said area of said porous barrier.
[FR] L'invention concerne un procédé, un ensemble et un dispositif permettant de réguler le flux de liquide d'imprégnation à travers une barrière poreuse adaptable semi-perméable, ce procédé consistant à préparer la formulation par suspension ou dispersion de ces liquides d'imprégnation dans un liquide polaire sous forme de gouttelettes fluides entourées par un revêtement de type membrane d'une ou plusieurs couches, ce revêtement comprenant au moins deux types ou formes de substances amphiphiliques ayant tendance à s'agréger, à transporter les agents à travers les pores de cette barrière ou à permettre leur perméation à travers les pores de cette barrière une fois que les liquides d'imprégnation sont entrés dans les pores ; à sélectionner une quantité de ces liquides d'imprégnation à appliquer sur une zone prédéterminée de cette barrière pour réguler le flux de ces liquides d'imprégnation à travers cette barrière et à appliquer la quantité sélectionnée de cette formulation contenant ces liquides d'imprégnation sur la zone de cette barrière poreuse. |
