Working patterns: Size-controllable electrochemical deposition of conducting polymer micropatterns across individually addressable electrode junction pairs (inset) is achieved with a hydrodynamically focused laminar stream in a microfluidic setting (see picture). Such a focused stream can be used as a dynamic template for sequential production of sensor arrays capable of detecting extremely small quantities of analytes.
