Method and apparatus for programmable fluidic processing
View Patent ↗A method and apparatus for microfluidic processing by programmably manipulating a packet. A material is introduced onto a reaction surface and compartmentalized to form a packet. A position of the packet is sensed with a position sensor. A programmable manipulation force is applied to the packet at the position. The programmable manipulation force is adjustable according to packet position by a controller. The packet is programmably moved according to the programmable manipulation force along arbitrarily chosen paths.
1. An apparatus for manipulating a packet, the apparatus comprising:
a reaction surface;
a force generator comprising a light source and a plurality of conductors, the plurality of conductors coupled to the reaction surface;
a controller coupled to the force generator to generate one or more forces capable of imparting forces on a packet to move the packet along arbitrarily chosen paths about the reaction surface.
2. The apparatus of claim 1 , further comprising:
a position sensor configured to track positions of the packet along arbitrarily chosen paths about the reaction surface;
where the controller is coupled to the position sensor and configured to adjust the forces according to the positions such that the packet moves along the arbitrarily chosen paths.
3. The apparatus of claim 2 , where the plurality of conductors and the position sensor are integral.
4. The apparatus of claim 2 , where the position sensor comprises a plurality of conductors configured to measure an electrical impedance of the packet.
5. The apparatus of claim 2 , where the position sensor comprises an optical system configured to monitor the position of the packet.
6. The apparatus of claim 2 , further comprising:
an inlet port coupled to said reaction surface and configured to introduce a packet onto the reaction surface.
7. The apparatus of claim 6 , further comprising:
an outlet port coupled to the reaction surface and configured to collect a packet from the reaction surface.
