15. A composite structure prepared by a low temperature bonding method, wherein the composite structure is prepared by a process comprising:
-
providing first and second impermeable mating pieces, the first and second mating pieces in combination forming a channel structure;
applying an aqueous solution of a bonding agent;
eliminating excess water from the applied aqueous solution to form a thin layer on the first mating piece, wherein the thin layer is a film of a least one molecular layer in thickness which covalently bonds to the first mating piece with a reactive moiety at one position on the molecule and covalently bonds to the second mating piece with a reactive moiety at another position on the molecule; and
bringing the second mating piece in contact with the first mating piece with the thin layer in between, wherein the bonding method provides for strong bonds at temperatures of 90°

20. A device comprising biomolecules or diagnostic chemical arrays of binding moieties, wherein the device has a tri-layer structure, wherein a impermeable first layer is in a mating position with respect to a impermeable third layer, wherein at least one of the first layer or the third layer includes a channel structure and biomolecules or diagnostic chemical arrays of binding moieties located within at least a portion of the channel structure, wherein the channel structure is a groove located on an interior surface of the first or third layer, and wherein the mated first and third layers are bonded by a thin layer of dried silicate disposed between the first and third layers, wherein the thin layer forms a second layer and wherein the bonding is carried out at temperatures of 90°
- C. or less.
