CaCO3 particles, due to their unique properties such as biodegradation, pH-sensitivity, and porous surface, have been widely used as carrier materials for delivering drugs, genes, vaccines, and other bioactive molecules. In these applications, CaCO3 particles are often administered intravenously. In this sense, the interaction between CaCO3 particles and blood components plays a key role in their delivery efficacy and biosafety, though the hemocompatibility of CaCO3 particles has not been evaluated until now. Deficiency in the biosafety informa...
