Irradiated agarose, compositions thereof, and related methods

Irradiated agarose gels and compositions containing irradiated agarose gels are described, along with methods of production and use. Methods of forming an irradiated agarose composition include irradiating an agarose in dry form to produce an irradiated agarose, dissolving the irradiated agarose in a solvent to form a solution containing irradiated agarose, and gelling the solution containing irradiated agarose to form a gel containing irradiated agarose. The resulting gel containing irradiated agarose may have a reduced gel strength, making it more suitable for use as an injectable, even at high concentrations.
