Mesoporous nano-hydroxyapatite (n-HAP) was expeditiously synthesized using the pseudo sol-gel microwave-assisted protocol (30 min) in the presence of two novel templates, namely sodium lauryl ether sulfate (SLES) and linear alkylbenzenesulfonate (LABS). The cooperative self-assembly of the calcium precursor with the surfactant molecules followed by the interaction with PO43- ligand led to the formation of mesoporousnano-hydroxyapatite (n-HAP) with controlled pore sizes. The systematic use of these surfactants in combination with microwave energy input enables the precise control of pore size in a narrow-size distribution range (35 nm) which were fully characterized.
