Axisymmetric polydimethysiloxane microchannels for in vitro hemodynamic studies [PDF]
The current microdevices used for biomedical research are often manufactured using microelectromechanical systems (MEMS) technology. Although it is possible to fabricate precise and reproducible rectangular microchannels using soft lithography techniques,

Polydimethylsiloxane (PDMS)-based microfluidic channel with integrated commercial pressure sensors [PDF]
The precise characterisation of boiling in microchannels is essential for the optimisation of applications requiring two phase cooling. In this paper polydimethylsiloxane (PDMS) is employed to make microchannels for characterising microboiling.

Effect of microchannel aspect ratio on residence time distributions and the axial dispersion coefficient [PDF]
The effect of microchannel aspect ratio (channel depth/channel width) on residence time distributions and the axial dispersion coefficient have been investigated for Newtonian and shear thinning non-Newtonian flow using computational fluid dynamics.
