Abstract
A method of preserving a biological material includes the steps of providing at least one fiber-forming material, mixing at least one biological material, and optionally, one or more additives, to the at least one fiber-forming material to form a mixture, and forming at least one fiber from the mixture, wherein the resulting fiber has a diameter between 0.3 nanometers and about 25 microns. A biological material preserved by this method is also disclosed.
Claims22
A method of preserving a biological material in a dry protective matrix comprising the steps of:
- providing at least one fiber-forming material;
- mixing at least one biological material, and optionally, one or more additives, to the at least one fiber-forming material to form a mixture;
- forming at least one fiber from the mixture, wherein the fiber has a diameter between about 0.3 nanometers and about 25 microns;
- and
- hardening and/or drying said at least one fiber to thereby provide a biological material embedded in a dry protective matrix.
A method of preserving a biological material comprising the steps of:
- providing at least one fiber-forming material selected from the group consisting of poly (vinyl pyrrolidone), polyethyl oxazoline, polyethylenimine, polyethylene oxide, and mixtures and copolymers thereof;
- mixing at least one biological material, and optionally, one or more additives, to the at least one fiber-forming material to form a mixture;
- and
- forming at least one fiber from the mixture, wherein the fiber has a diameter between about 0.3 nanometers and about 25 microns.
