Hydroxyapatite Nanoparticle Coating on Polymer for Constructing Effective Biointeractive Interfaces

الملخص EN

Bone is an organic-inorganic composite with the ability to regenerate itself.

Thus, several studies based on artificial organic-inorganic interface sciences have been tried to develop capable materials for effective regenerative bone tissues.

Hydroxyapatite nanoparticles (HAp NPs) have extensively been researched in bone tissue engineering due to the compositional and shape similarity to the mineral bone and excellent biocompatibility.

However, HAp alone has low mechanical strength, which limits its applications.

Therefore, HAp NPs have been deposited on the biocompatible polymer matrix, obtaining composites with the enhanced mechanical, thermal, and rheological properties and with higher biocompatibility and bioactivity.

For developing new biomedical applications, polymer-HAp interfacial interactions that provide biofusion should be investigated.

This paper reviewed common coating techniques for obtaining HAp NPs/polymer fusion interfaces as well as in vitro studies of interfacial interactions with proteins and cells, demonstrating better biocompatibility.

Studies based on interfacial interactions between biomolecules and HAp NPs were highlighted, and how these interactions can be affected by specific protein preadsorption was also summarized.
