A liquid embolic material may include a mixture of a first solution comprising between about 1.2% and about 2.5% weight per volume (w/v) carboxymethyl chitosan (CCN) in a first solvent and a second solution comprising between about 1.2% and about 2.5% w/v oxidized carboxymethyl cellulose (OCMC) in a second solvent. The liquid embolic material may be used to embolize a targeted embolization location by mixing the first solution and the second solution to form a liquid embolic material (or hydrogel precursor material), introducing the hydrogel precursor material to a targeted embolization location within a body of a patient, and allowing the CCN and the OCMC to react to form the hydrogel material and embolize the targeted embolization location.
