Abstract
A patterned capillary device comprising a pattern on an inner surface is described herein. More specifically, the patterned capillary device comprises a wall having an outer surface and an inner surface, the wall defining a fluidic channel. A substantially opaque film covers the inner surface of the wall, the opaque film comprising a plurality of substantially transparent segments defining a pattern. A process for fabricating a pattern formed of opaque and transparent portions on an inner surface of a capillary device is also described herein.
Claims14
A process for fabricating a patterned capillary device, the process comprising:
- thiolating an inner surface of the capillary;
- exposing a plurality of segments of the capillary to a source of radiation, the plurality of exposed segments defining a pattern, wherein the pattern extends circumferentially around the inner surface of the capillary;
- and
- flowing a solution comprising gold seeds though the capillary, the seeds adhering to non-exposed segments of the inner surface.
