Collagen gels are flowable, suggesting the possibility of an easily injectable, biocompatible drug delivery matrix. Sustained release of therapeutic molecules from collagen matrices, however, is beset with difficulties. Fibrillar collagen gels have a

A rapidly gelling synthetic tissue sealant was developed from tetra-succinimidyl and tetra-thiol-derivatized polyethylene glycol (PEG). The two reagents were dissolved in aqueous buffers at 20% (w/v) solids and sprayed on the tissue site, with the us

Injectable collagen is a concentrated dispersion of collagen fibers in aqueous solution that is used to correct dermal contour defects through intradermal injection. The effect of hydrophobic forces on the rheology of concentrated dispersions of coll

Collagen-silicone composites were fabricated and tested for biocompatibility by subcutaneous implantation in rats. The silicone component consisted of addition cure or condensation cure sheets. The collagen component was either (a) a sponge layer 2 m

Electrostatic energies of interaction between type I collagen molecules were calculated, using models developed by Timasheff and Hill. These energies, along with a contribution from hydrophobic forces, were then incorporated into an equation due to F

A method was developed for computing the free energy (delta Fi) of aggregates of type I collagen. The method was based on a treatment of Matheson and Flory describing phase equilibria of rigid rod polymers. It included a polymer-solvent interaction t

A quantitative model for fibril assembly of type I collagen was extended to include the explicit effect of extrahelical peptides. The collagen molecule was simulated by rod-like sequences to which short, rigid tails were connected by "nondimensional"
