A review on injectable hydrogels from xanthan gum for biomedical applications

Xanthan gum (XG) is recognised as one of the most popular natural polymers extensively used today due to its biode-gradable and biocompatible properties, and, therefore, XG can be used to produce hydrogels with other polymers to expand its uses. However, at present, there has not been much research on preparing injectable hydrogels from XG. Moreover, up to now, there are only a limited number of review articles related to this topic. This review will provide a well-organised and somewhat extensive presentation of previous studies that have been executed on injectable hydrogels from XG. Also, applications have been using XG to fabricate injectable hydrogels such as cartilage tissue engineering, bone tissue engineering, delivery system, and bioink will be reviewed.
