Abstract
Some embodiments of a micro-fluidic device include at least one inlet hole located on an inlet side of the microfluidic device, the inlet hole consisting of a plurality of holes with diameters smaller in size than a diameter of the at least one inlet hole, at least one outlet hole located on an outlet side of the microfluidic device opposite the inlet side; and a micro-channel, where the plurality of holes are connected to the micro-channel.
Claims20
A microfluidic system comprising:
- a microfluidic device including:
- at least one open inlet hole located on an inlet side of the microfluidic device and open to the atmosphere, the inlet hole including a plurality of holes with diameters smaller in size than a diameter of the at least one inlet hole;
- at least one outlet hole located on an outlet side of the microfluidic device opposite the inlet side;
- and
- a micro-channel facilitating fluid communication between the at least one open inlet hole and the at least one outlet hole,
- wherein the plurality of holes are positioned relative to the micro-channel to enable access to the micro-channel such that the fluid passes through each of the plurality of holes in parallel;
- and
- a pressure source directly connected to the at least one outlet hole and configured to supply pressure to the micro-channel.

A method comprising:
- dispensing a liquid into a microfluidic device, wherein the microfluidic device includes
- at least one inlet hole located on an inlet side of the microfluidic device and open to the atmosphere, the inlet hole including a plurality of holes with diameters smaller in size than a diameter of the at least one inlet hole;
- at least one outlet hole located on an outlet side of the microfluidic device opposite the inlet side;
- and
- a micro-channel, wherein the plurality of holes enable access to the micro-channel,
- wherein the plurality of holes are positioned relative to the micro-channel to enable access to the micro-channel such that the fluid passes through each of the plurality of holes in parallel;
- and
- supplying pressure to the micro-channel using a pressure source directly connected to the at least one outlet hole.
5 more elements
A microfluidic system comprising:
- a microfluidic device including:
- an open well configured to receive a liquid and open to the atmosphere;
- a micro-channel;
- a plurality of channels disposed between the open well and the micro-channel, where the plurality of channels are smaller in size than the micro-channel;
- and
- at least one outlet hole located on an outlet side of the microfluidic device opposite a side of the open well,
- wherein the micro-channel facilitates liquid communication between the open well and the at least one outlet hole,
- wherein the plurality of channels are positioned relative to the micro-channel to enable access from the open well to the micro-channel such that the fluid passes through each of the plurality of channels in parallel;
- and
- a pressure source directly connected to the at least one outlet hole and configured to supply pressure to the micro-channel.
