Hydroxyapatite-polyethylene composites for bone substitution: effects of ceramic particle size and morphology.

abstract：:Bioactive hydrogels formed from the Michael-type addition reactions of end-functionalized poly (ethylene glycol) macromers with thiol-containing protease-sensitive peptide crosslinkers have previously been described as matrices for cell-induced enzymatic remodeling. In this study, we sought to develop materials formul...
