Abstract
Compositions and related methods are described. The composition may include a polysaccharide, a crosslinker, and an imaging agent. For example, the composition may include from about 0.1 wt% to about 25 wt% of an imaging agent, based on a total weight of the composition. The polysaccharide may include chitosan or gellan gum. The imaging agent may include a radiopaque material or an echogenic material. The composition may be biocompatible and formulated as a gel.
Claims20
A composition comprising:
- a polysaccharide comprising chitosan or gellan gum;
- a crosslinker;
- and
- from about 0.1 wt% to about 25 wt% of an imaging agent, based on a total weight of the composition, wherein the imaging agent comprises a radiopaque material or an echogenic material;
- wherein the composition is biocompatible and formulated as a gel.
A composition comprising:
- a polysaccharide comprising chitosan or gellan gum;
- a crosslinker comprising trilysine or a polyethylene glycol (PEG) polymer that includes a plurality of succinimidyl groups;
- and
- from about 0.1 wt% to about 25 wt% of an imaging agent, based on a total weight of the composition, wherein the imaging agent comprises a radiopaque material that includes a metal or the imaging agent comprises an echogenic material.
