Abstract
The invention concerns a method for isolating an analyte from an initial sample containing same, on a reactive surface in contact with all or part of the initial sample, characterized in that it comprises the following steps which consist in: 1) forming and/or maintaining a reaction volume entity, comprising an internal liquid medium, corresponding to all or part of the initial sample, the entity including an interface with an external medium, having with the latter a surface tension; 2) applying a temperature difference between at least two thermal points located: a) proximate to and/or b) on the surface and/or c) within said entity, said thermal points being respectively different, in terms of temperature and positioning; 3) fixing the analyte on the reactive surface, positioned on the path of forces convection generated by the temperature difference.
