Patent ID: 7713485

Claim:
A microfluidics switch with moving planes, comprising: a first substrate having a first hydrophobic plane, said first hydrophobic plane having a plurality of input holes and at least one output hole passing through said first substrate, said plurality of input holes and said at least one output hole being isolated from each other, wherein said plurality of input holes comprise a first hole, a second hole, and a third hole; and a second substrate having a second hydrophobic plane, said second hydrophobic plane having a pit for reaction, a plurality of input microfluidics channels, and at least one output microfluidics channel, said plurality of input microfluidics channels and said at least one output microfluidics channel connecting with said pit; wherein said first hydrophobic plane of said first substrate is faced to and sliding contact with said second hydrophobic plane of said second substrate, said first substrate is capable of moving parallel to said second hydrophobic plane of said second substrate to a first relative position or a second relative position so as to control the overlap relationship between said plurality of holes and said plurality of microfluidics channels, a fluid channel is formed while at least one of said plurality of input holes is overlapped with at least one of said plurality of input microfluidics channels and at least one of said at least one output hole is overlapped with at least one of said at least one output microfluidics channel, wherein said first hole is communicated with said pit, said second hole is not communicated with said pit, and said third hole is communicated with said pit in said first relative position, and wherein said first hole is not communicated with said pit, said second hole is communicated with said pit, and said third hole is communicated with said pit in said second relative position.
