In order to bring widely distributed polysaccharides materials into more medical applications, cotton fiber surfaces were modified into substrates for apatite deposition. Using a solid phase reaction, cotton fibers were conveniently carboxylated in large scale. The carboxylated cotton fibers were coated by apatite in a biomimetic way. Through soaking in a concentrated simulated body fluid (SBF × 5), nano-size apatite particles rapidly and finely grew on the fiber surfaces. The nucleation and growth of apatite was investigated with the aid of scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). In comparison to pure cotton, the cotton coated with apatite showed improved cell affinity to osteoblast-like cells.
