Abstract

Methods of forming a chip with fluidic channels include forming (e.g., milling) at least one nanofunnel with a wide end and a narrow end into a planar substrate, the nanofunnel having a length, with width and depth dimensions that both vary over its length and forming (e.g., milling) at least one nanochannel into the planar substrate at an interface adjacent the narrow end of the nanofunnel.
