Preparation of hydroxyapatite nanoparticle-hyaluronic acid hybrid membranes through citric acid molecular mediation†
Abstract
Citric acid (Cit)-coordinated hydroxyapatite (HAp) nanoparticles (NPs) were nanohybridized with hyaluronic acid (HYA) to form transparent membranes, where hydrogen bonds were formed between the NPs and HYA to change the hydration states. The interactions by the mediated Cit were found to be important for the nanohybridization between HAp and HYA.
