Abstract
Provided is a method of forming a fibrinogen hydrogel composition, the method including providing a fibrinogen hydrogel or precursor thereof, comprising fibrinogen hydrogel forming salt. The fibrinogen hydrogel forming salt concentration is greater than or equal to the threshold concentration to form a fibrinogen hydrogel. The method further includes denaturing the fibrinogen hydrogel such as by heating. The method optionally further includes combining the fibrinogen hydrogel with a carrier material. When present, the concentration of the carrier material typically ranges from 0.1 to about 50 wt.-%. The method further includes reducing the salt concentration below the threshold concentration to form a fibrinogen hydrogel.
