Preparation of mesoporous calcium phosphates

Abstract

Phosphate salts of calcium such as tricalcium phosphate (TCP) and hydroxyapatite (HAp) are well known as excellent bioceramics. They can conjugate with human hard tissues in the human body (bioactivity). HAp has also been used as a drug carrier, absorbent, and catalytic support. Recently, mesoporous silica with a periodic hexagonal nano-channel structure, for example, MCM-41, is prepared using surfactant aggregates as a template. However, very few studies have been reported on the preparation of mesoporous calcium phosphate. In this study we tried to prepare mesoporous calcium phosphate using surfactant aggregates as a template.
