Method for handling microdrops which include samples

Abstract

A method for handling, in a microfluidic system, microdrops which include samples, including the steps of forming, in an oil, microdrops of an aqueous solution containing a sample, the oil and/or the aqueous solution containing a sample including a gelling agent; trapping the microdrops by means of surface-tension traps pre-arranged in a trapping area; and at least partially gelling the oil in the trapping area and/or at least partially gelling the trapped microdrops
