Abstract

Provided is a micro- and nano-fluidic chip, including at least one nanochannel array layer and at least one microchannel array layer that are alternately stacked. The at least one nanochannel array layer includes nanochannels, the at least one microchannel array layer includes input units and/or output units. The input unit includes inlet microchannel arrays and inlets, and the output unit includes outlet microchannel arrays and outlets. The inlet microchannel array includes inlet microchannels, the outlet microchannel array includes outlet microchannels, and the inlet microchannels and the outlet microchannels are connected through the nanochannels.
