Mineralization of hydroxyapatite upon a unique xanthan gum hydrogel by an alternate soaking process.

Highlights: [•] A unique xanthan gum (Xan) hydrogel was subjected to an alternate soaking process. [•] Hydroxyapatite (Hap) was mineralized upon the Xan-matrix surface by the process. [•] The mineralization induced a microstructure change in the gel-matrix. [•] The resulting Hap–Xan composite hydrogel showed good mechanical property. [ABSTRACT FROM AUTHOR]
