This work describes the fabrication of thin microfluidic devices in Kapton (polyimide). These
chips are well-suited to perform X-ray scattering experiments using intense microfocussed beams,
as Kapton is both relatively resistant to the high intensities generated by a synchrotron, and
almost transparent to X-rays. We show networks of microchannels obtained using laser ablation
of Kapton films, and we also present a simple way to perform fusion bonding between two
Kapton films. The possibilities offered using such devices are illustrated with X-ray scattering
experiments. These experiments demonstrate that structural measurements in the 1A ? 20nm
range can be obtained with spatial resolutions of a few microns in a microchannel.
