Project status In implementation
Project goal/description The project aims to develop a new concept for the processing of eggshells into next-generation biomaterials for bone regeneration. Although a wide range of information is available on the use of eggshells in the synthesis of calcium phosphates (CaP), such as hydroxyapatite and tricalcium phosphate, the use of eggshells for the production of amorphous calcium phosphates (ACP) has not been extensively studied, mainly due to ACP metastability. As part of the project, chicken eggshells will be used as a raw material for the synthesis of a stable ACP phase, from which, for the first time, new, porous, natural bone-like ACP ceramic substrates will be obtained. In addition, to fully process chicken eggshells into high value-added products, proteins with high bioactive content and antibacterial properties will be extracted from eggshell membranes. The obtained proteins are intended to be used for coating porous ACP ceramic substrates, thus giving the material new and unique properties.
