Surface-initiated polymerization, microfluidic devices

Surface-initiated polymerization is an attractive method for fabrication of microfluidic devices [244—247]. For example, Xu et al. reported surface-initiated ATRP inside microchannels to produce flat gradient and patterned surfaces [248]. 

The use of a focused infrared laser beam on a surface results in local heating, which has been applied to synthesize MIPs locally by thermal polymerization [72]. In this case, a common thermo-initiator, azobisisobutyronitrile, was used together with a standard MIP recipe, to generate MIP microdots in a microfluidic device.
