An injectable gellan gum-based hydrogel that inhibits Staphylococcus aureus for infected bone defect repair

The treatment of infected bone defects in complex oral and maxillofacial structures remains a challenge. An injectable gellan gum (GG)-based hydrogel loaded with nanohydroxyapatite particles and chlorhexidine (nHA/CHX) can accelerate the repair of infected bone defects.
