1. A kit comprising a polymeric surgical fastener having a functionalized surface including a plurality of reactive members of a specific binding pair and a container containing a liquid precursor including complementary reactive members of the specific binding pair, wherein upon interaction the reactive members and the complementary reactive members can bind to one another to form covalent bonds and the polymeric surgical fastener is selected from the group consisting of sutures, staples, clips, pins, hooks, screws, cables, and anchors. 2. A kit according to claim 1 further comprising a second container for containing a catalyst. 3. A kit according to claim 2 wherein the catalyst is a metal. 4. A kit according to claim 3 wherein the metal is a copper solution. 5. A kit according to claim 1 further comprising a device for delivering the liquid precursor to tissue. 6. A kit according to claim 5 wherein the device for delivering the liquid precursor to the tissue is a sprayer. 7. A kit according to claim 1 further comprising generator for generating microwaves or ultraviolet radiation. 8. A kit according to claim 1 wherein the surgical fastener comprises a staple. 9. A kit according to claim 1 further comprising a delivery device adapted to implant the surgical fastener. 10. The kit according to claim 9 wherein the delivery device is a surgical stapling device. 11. A kit according to claim 1 wherein the members of the specific binding pair bind to one another via a reaction selected from the group consisting of Huisgen cycloaddition reaction, a Diels-Alder reaction and a thiol-ene reaction. 12. A kit according to claim 11 wherein the reaction is catalyzed by copper to activate an alkyne and an azide for [3+2] cycloaddition. 13. A kit according to claim 11 wherein the reaction involves a cyclooctyne reagent and an azide for [3+2] cycloaddition. 14. A kit according to claim 1 wherein the members of the specific binding pair are alkynes and azides. 15. A kit according to claim 1 wherein the members of the specific binding pair are thiols and alkenes. 16. A kit according to claim 1 wherein the members of the specific binding pair are dienes and alkenes. 17. A kit according to claim 1 wherein the complementary reactive members of the liquid precursor are conjugated to a linker adapted to link the complementary reactive members to tissue. 18. A kit according to claim 17 wherein the complementary reactive members are linked to the tissue via an RGD linker. 19. A kit according to claim 17 wherein the complementary reactive members are conjugated to a linker selected from the group consisting of antibody, Fab, F(ab′)2, Fv, single chain antibody (SCA) and single complementary-determining region (CDR). 20. A kit according to claim 1 wherein the surgical fastener is provided with the reactive members of the specific binding pair by surface modification techniques selected from the group consisting of physical vapor deposition, chemical vapor deposition, plasma treatments, coupling treatments, acid hydrolysis and base hydrolysis. 21.
