Abstract
Method of manufacturing a microscale nozzle, comprising the steps of forming a microscale channel in the top surface of a substrate, said microscale channel comprising an inlet end and a nozzle-end, depositing a nozzle-forming layer in a section of the microscale channel, and removing material from the substrate at the nozzle-end of the microscale channel to expose at least a portion of said nozzle-forming layer. The manufactured microscale nozzle may be used for transferring a liquid sample form a microchip fluidic system into an external analytical device.
