Multi-Level 3D Implementation of Thermo-Pneumatic Pumping on Centrifugal Microfluidic CD Platforms
Thermo-pneumatic (TP) pumping is a method employing the principle of expanding heated air to transfer fluids back towards the CD center on the centrifugal microfluidic CD platform. While the TP features are easy to fabricate as no moving parts are involved, it consumes extra real estate on the...

| description | Thermo-pneumatic (TP) pumping is a method
employing the principle of expanding heated air to transfer
fluids back towards the CD center on the centrifugal
microfluidic CD platform. While the TP features are easy to
fabricate as no moving parts are involved, it consumes extra
real estate on the CD, and because heating is involved, it
introduces unnecessary heating to the fluids on the CD. To
overcome these limitations, we introduce a multi-level 3D
approach and implement forced convection heating. In a multi-level 3D CD, the TP features are relocated to a separate top
level, while the microfluidic process remains on a lower bottom
level. This allows for heat shielding of the fluids in the
microfluidic process level, and also improve usage of space on
the CD. To aid in future implementations of TP pumping on a
multi-level 3D CD, studies on the effect of heat source setting,
and the effect of positioning the TP feature (it distance from the
CD center) on CD surface heating are also presented. In this
work, we successfully demonstrate a multi-level 3D approach to
implement TP pumping on the microfluidic CD platform. |
