1. A microfluidic device, comprising:

  • a) a first and a second substrate;

    b) a fluid channel;

    c) at least a channel and one or more fluid ports etched in the first and/or second substrates;

    d) a first layer deposited on a surface of the second substrate, from which the first layer is partially removed in accordance with a predefined geometry; and

    e) a second layer deposited on top of the first layer and the surface of the second substrate;

    wherein the first substrate is aligned relative to the surface of the second substrate and thereafter bonded therewith, and wherein the first layer is arranged relative to the channel so as to influence the transport or the properties of the fluid in the channel.
