    摘要: A lab-on-a-chip comprising a support plate, at least one fluidic network formed in a fluidic plate bonded onto the support plate, and a cover plate bonded onto the fluidic plate and covering the fluidic network. The fluidic network, at a first end, is connected to an inlet orifice allowing entry of a liquid to be sprayed and, at a second end, to a first end of an outlet channel for the liquid to be sprayed, formed in the fluidic plate. The fluidic plate is extended by a pointed electrospray nozzle at which the second end of the outlet channel forms the electrospray outlet of the lab-on-a-chip. The cover plate has a pointed extension forming a roof for that part of the channel located in the electrospray nozzle.
