| Résumé : |
Collagen dispersions, produced from fibrils recovered from milled bovine collagen, have shown promise in environmental remediation in applications as settling aids, filtration aids, fractionation media, oil drop stabilizers, and water purification aids. Macroporous structures, processed by controlled lyophilization of collagen dispersions, are suitable as cell culturing substrates. Collagen was structurally characterized during milling to assist in designing a method for scale-up of the production process. In fact, although the initial processing involves a ball mill, the actual operation is more of an unraveling of the fiber to expose the fibrils, which have nanoscale dimensions. During the ball-milling step of production the active surface area of the collagen increases more than 200 times without chemically altering or denaturing the collagen. To demonstrate this throughout the milling process, active surface area per mass, fibril structure, molecular weight distribution, percent lipid, percent nitrogen, and percent ash were monitored. |
