Claims
- 1. A composition of matter comprising a glass surface bonded to a silane coupling agent having a thiocarbamate group, said thiocarbamate group bonded to a layer of poly(N-isopropylacrylamide) and a cross linking agent.
- 2. The composition of matter of claim 1 wherein said glass is selected from the group consisting of silicon dioxide, boric oxide, aluminum oxide, and phosphorus pentoxide.
- 3. The composition of matter of claim 1 wherein said crosslinking agent is selected as an organic molecule having an acrylamide group and at least two double bonds in said organic molecule's structure.
- 4. The composition of matter of claim 3 wherein said crosslinking agent is N,N′-methylenebisacrylamide.
- 5. The composition of matter of claim 1 wherein said silane coupling agent is (N,N′-diethylamine) dithiocarbamoylpropyl-(trimethoxy) silane.
- 6. A microchannel filter comprising a glass microchannel surface bonded to a silane coupling agent having a thiocarbamate group, said thiocarbamate group bonded to a layer of poly(N-isopropylacrylamide) and a cross linking agent.
- 7. The microchannel filter of claim 6 wherein said glass is selected from the group consisting of silicon dioxide, boric oxide, aluminum oxide, and phosphorus pentoxide.
- 8. The microchannel filter of claim 6 wherein said crosslinking agent is selected as an organic molecule having an acrylamide group and at least two double bonds in said organic molecule's structure.
- 9. The microchannel filter of claim 8 wherein said crosslinking agent is N,N′-methylenebisacrylamide.
- 10. The microchannel filter of claim 6 wherein said silane coupling agent is (NN′-diethylamine) dithiocarbamoylpropyl-(trimethoxy) silane.
- 11. A capillary fluid pump comprising a glass capillary having an interior and an exterior surface wherein said interior surface is bonded to a silane coupling agent having a thiocarbamate group, said thiocarbamate group bonded to a thin layer of poly(N-isopropylacrylamide).
- 12. The capillary fluid pump of claim 11 wherein said glass is selected from the group consisting of silicon dioxide, boric oxide, aluminum oxide, and phosphorus pentoxide.
- 13. The capillary fluid pump of claim 11 wherein said crosslinking agent is selected as an organic molecule having an acrylamide group and at least two double bonds in said organic molecule's structure.
- 14. The capillary fluid pump of claim 13 wherein said crosslinking agent is N,N′-methylenebisacrylamide.
- 15. The capillary fluid pump of claim 11 wherein said silane coupling agent is (N,N′-diethylamine) dithiocarbamoylpropyl-(trimethoxy) silane.
