A microfluidic apparatus for delivering droplets of a first fluid to droplets of a second fluid, comprising a main channel, with a carrier fluid carrying droplets of the second fluid, an auxiliary channel, fluidly coupled to the main channel at a first intersection via a first orifice with a first fluid interface, and at a second intersection downstream to the first intersection via a second orifice with a second fluid interface, wherein a flow of the carrier fluid induces a difference of pressure between the first and second orifice generating a balance condition such that a meniscus of the second fluid interface is maintained in the auxiliary channel, at the vicinity of the second orifice, wherein a balance deviation triggers a release of a volume of the first fluid from the second fluid interface into the main channel.
