Abstract
A method of introducing an additive to a biological material using a supercritical fluid is disclosed. The method comprises placing the biological material in a processing chamber, adding an additive to the supercritical fluid to form a supercritical fluid-additive mixture, adding the supercritical fluid-additive mixture to the processing chamber, and pulsing the mixture in the processing chamber. A processing system for introducing an additive to a biological material using a supercritical fluid in accordance with the present invention comprises a processing chamber for housing the biological material, a vat for storing a processing fluid, a pump, a heating element, an inlet port, and a flow path.
Claims19
A method of infusing a protein into bone material comprising:
- a) introducing bone material into a processing chamber;
- b) introducing a mixture of a supercritical fluid and the protein into the processing chamber;
- and
- c) performing a pulsing step on the mixture such that the supercritical fluid fluctuates between its nonsupercritical state and its supercritical state, wherein some of the protein is infused into the bone material and some remains in the supercritical fluid, thereby forming an infused bone material comprising a portion of the protein.
