Method for handling at least one first microdrop and at least one second microdrop in a microfluidic system including a capillary trap that has a first trapping zone and a second trapping zone, the method including steps consisting of: (i) trapping the first microdrop in the first trapping zone, and (ii) trapping the second microdrop in the second trapping zone, the first and the second trapping zone being arranged such that the first and the second microdrops are in contact with each other, the first and the second trapping zones being adapted such that the trapping forces returned to one of the microdrops are different.

Microfluidic method for handling microdrops

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.
