1. A biocompatible composition comprising: an implant comprising a substrate;a first component comprising a biodegradable material including a tissue binding end group and a functional group selected from the group consisting of biotin and avidin; anda second component comprising a biodegradable material including a substrate binding end group and a functional group selected from the group consisting of biotin and avidin,wherein the biodegradable material of the first component, the second component, or both, is selected from the group consisting of polylactides, poly(lactic acid), polyglycolides, poly(glycolic acid), poly(trimethylene carbonate), poly(dioxanone), poly(hydroxybutyric acid), poly(hydroxyvaleric acid), poly(lactic-co-glycolic acid), poly(lactide-co-(ε-caprolactone-)), poly(glycolide-co-(ε-caprolactone)), polycarbonates, poly(pseudo amino acids), poly(amino acids), poly(hydroxyalkanoate)s, polyalkylene oxalates, polyoxaesters, polyanhydrides, polyester anyhydrides, polyortho esters, and copolymers, block copolymers, homopolymers, blends, and combinations thereof, andwherein the functional group of the first component is different than the functional group of the second component and the first component adheres to a tissue surface and the second component adheres to the implant. 2. The biocompatible composition according to claim 1, wherein the implant is a tissue engineered construct. 3. The biocompatible composition according to claim 2, wherein the tissue engineered construct is selected from the group consisting of foams, films, tissue scaffolds, pledgets, buttresses, and meshes. 4. The biocompatible composition according to claim 1, wherein the tissue binding end group of the first component is a functional group of a macromolecule. 5. The biocompatible composition according to claim 1, wherein the substrate binding end group of the second component is a functional group of a macromolecule. 6. The biocompatible composition according to claim 1, wherein at least one of the tissue binding end group and the functional group of the first component is covalently bound to a macromolecule. 7. The biocompatible composition according to claim 1, wherein at least one of the substrate binding end group and the functional group of the second component is covalently bound to a macromolecule. 8. The biocompatible composition according to claim 1, wherein at least one of the tissue binding end group and the functional group of the first component is conjugated to a macromolecule through a linking agent. 9. The biocompatible composition according to claim 1, wherein at least one of the substrate binding end group and the functional group of the second component is conjugated to a macromolecule through a linking agent. 10. The biocompatible composition according to claim 1, further comprising a bioactive agent. 11. The biocompatible composition according to claim 1, wherein the tissue binding end group and the substrate binding end group are each selected from the group consisting of amine, carboxyl, and hydroxyl groups. 12. A method for adhering an implant to tissue comprising: applying a first component comprising a biodegradable material including a tissue binding end group and a functional group selected from the group consisting of biotin and avidin to a tissue surface;applying a second component comprising a biodegradable material including a substrate binding end group and a functional group selected from the group consisting of biotin and avidin to an implant comprising a substrate, wherein the functional group of the first component is different than the functional group of the second component; andcontacting the tissue surface with the implant to adhere the implant to the tissue via avidin-biotin affinity binding,wherein the biodegradable material of the first component, the second component, or both, is selected from the group consisting of polylactides, poly(lactic acid), polyglycolides, poly(glycolic acid), poly(trimethylene carbonate), poly(dioxanone), poly(hydroxybutyric acid), poly(hydroxyvaleric acid), poly(lactic-co-glycolic acid), poly(lactide-co-(ε-caprolactone-)), poly(glycolide-co-(ε-caprolactone)), polycarbonates, poly(pseudo amino acids), poly(amino acids), poly(hydroxyalkanoate)s, polyalkylene oxalates, polyoxaesters, polyanhydrides, polyester anyhydrides, polyortho esters, and copolymers, block copolymers, homopolymers, blends, and combinations thereof. 13. The method of claim 12, further comprising: applying the first component to a second tissue surface; andcontacting the first and second tissue surfaces with the implant to adhere the implant to both tissue surfaces. 14. A biocompatible composition comprising: an implant comprising a substrate;a first component comprising a biodegradable material including a tissue binding end group and a functional group selected from the group consisting of biotin and avidin; anda second component comprising a biodegradable material including a substrate binding end group and a functional group selected from the group consisting of biotin and avidin,wherein the biodegradable material of the first component, the second component, or both, is selected from the group consisting of alginate, dextran, chitin, chitosan, hyaluronic acid, cellulose, collagen, gelatin, fucans, glycosaminoglycans, catgut, silk, linen, cotton, albumin, casein, zein, silk, soybean protein, and copolymers and blends thereof, andwherein the functional group of the first component is different than the functional group of the second component and the first component adheres to a tissue surface and the second component adheres to the implant.
