Abstract

Proposed is a nanofluidic device (20) comprising a first microchannel (31 ), a first branch nanochannel (33) branching off the first microchannel (31 ), a second microchannel (32), a second branch nanochannel (34) branching off the second microchannel (32), and a mixing nanochannel (36). The mixing nanochannel hydraulic resistance is at least one thousand times larger than each of the first and second microchannel hydraulic resistance. A junction (35) is provided which connects the first branch channel, the second branch channel and the mixing nanochannel. The junction (35): - receives a first laminar fluid flow from the first branch nanochannel (33) and a second laminar fluid flow from the second branch nanochannel (34), and - contacts the first and second laminar fluid flows with each other to establish diffusion mixing of the first and second fluids, and - discharge the mixed first and second fluids into the mixing nanochannel inlet (36a).
