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 penerants 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.
本发明涉及一种控制渗透剂通过可适应的半渗透多孔屏障的方法、套件和装置,该方法包括以下步骤:制备配方,将渗透剂悬浮或分散在极性液体中,形成液滴,液滴周围有一层或多层膜状涂层,所述涂层包括至少两种具有聚集倾向的两性物质、所述渗透剂能够通过所述阻隔层的孔隙传输药剂,或在渗透剂进入孔隙后使药剂能够通过所述阻隔层的孔隙渗透,选择所述渗透剂的剂量用在所述阻隔层的预定区域,以控制所述渗透剂通过所述阻隔层的通量,并将选定剂量的含有所述渗透剂的所述制剂用在所述多孔阻隔层的所述区域。
