| description | One of the main challenges faced by researchers
in the field of microfluidic compact disc (CD) platforms is the
control of liquid movement and sequencing during spinning.
This paper presents a novel microfluidic valve based on the
principle of liquid equilibrium on a rotating CD. The proposed
liquid equilibrium valve operates by balancing the pressure
produced by the liquids in a source and a venting chamber
during spinning. The valve does not require external forces or
triggers, and is able to regulate burst frequencies with high
accuracy. In this work, we demonstrate that the burst
frequency can be significantly raised by making just a small
adjustment of the liquid height in the vent chamber. Finally,
the proposed valve ng method can be used separately or combined with other valving methods in advance microfluidic
processes. |
