Abstract

A microfluidic device having a plurality of microchannel structures and a memory. The memory may be writeable with restriction for unauthorized access. Yet further, the memory can be information about positions of non-redundant or redundant microchannel, information relating to positions for interfacing the microchannel structures with the macroworld, or supplemental information relating to process protocols that are allowed for the microchannel structures of the device.

Claims

1-16. -16. (canceled)

17. A microfluidic device comprising a plurality of microchannel structures having a redundancy that is ≦

50% and information that gives the position of redundant or non-redundant microchannel structures.

18. The microfluidic device of claim 17, wherein the information is placed in a memory on the device.

19. The microfluidic device of claim 17, wherein the information is separate from the device.

20. The microfluidic device of clam 17, wherein the number of disapproved microchannel structures is≦

the number of redundant microchannel structures.

21-25. -25. (canceled)

26. A microfluidic device comprising a plurality of microchannel structures and memory, wherein the memory comprises at least one of:

(a) information about the positions of at least one of;

(i) non-redundant microchannel structures or redundant microchannel structures; and

(ii) approved or disapproved microchannel structures;

(b) information relating to positions for interfacing the microchannel structures with the macroworld; and

(c) supplemental information relating to process protocols that are allowed for the microchannel structures.
