摘要： An article includes a microfluidic channel for moving fluid therethrough and at least one microfluidic actuator coupled to the microfluidic channel. The microfluidic actuator includes a deformable substance configured to enter the microfluidic channel to control fluid flow through the microfluidic channel. A method includes applying pressure to a deformable substance of a microfluidic actuator coupled to a microfluidic channel, such that the deformable substance of the microfluidic actuator enters the microfluidic channel. Another method includes inserting a needle into a microfluidic channel, applying pressure to a deformable substance of a microfluidic actuator coupled to the microfluidic channel, such that the deformable substance of the microfluidic actuator enters the microfluidic channel to form a seal around the needle, and injecting or extracting a fluid through the needle.
