Abstract: A composition for degrading biofilm structure associated with cystic fibrosis and the debris associated therewith comprises an enzyme selected for its ability to dismantle the biofilm structure, and an anchor molecule coupled to an enzyme to form an enzyme-anchor complex. The anchor molecule is selected for its ability to attach to a surface on or proximal the biofilm structure. The attachment to the surface permits prolonged retention time of the enzyme-anchor complex where the biofilm structure and associated debris are present.

Abstract: A two component composition comprises an anchor enzyme complex to degrade biofilm structures and a second anchor enzyme component having the capability to act directly upon the bacteria for a bactericidal effect.

Abstract: A composition for modulating bone regeneration composition comprises a matrix selected from the group consisting of glycolic acid, lactic acid, collagen, demineralized bone, or a combination thereof. A first biologically active molecule comprising a fibronectin is attached to a portion of the matrix, to facilitate osteoblast activity and for promoting an increase in bone formation. A second biologically active molecule comprising a vitronectin, selected for its ability to attract osteoclasts and produce an inhibiting effect on osteoclast activity to thereby promote a decrease in bone resorption, is also attached to a portion of the matrix.
