This study, we report the synthesis of silver and zinc co-doped nanosized hydroxyapatite (Ag-Zn-HAP) from the mixture of cheaply available calcium precursor of mussel shell (mollusk) with di-ammonium hydrogen phosphate (NH4)2HPO4 assisted by microwave irradiation. The grained powder of mussel shell was dissolved in diluted hydrochloric acid and di-ammonium hydrogen phosphate solution was slowly added to the mixture while maintaining the pH at 10 using ammonium hydroxide (NH4OH). Stoichiometric amount of Silver nitrate and zinc chloride was added followed by microwave irradiation for 30 min. The residue was collected and calcined at 900 °C for 2 h, after the decomposition of the organic fragments and carbonate phases; the expected silver and zinc doped hydroxyapatite was afford as nanorod of 20–50 nm scale with quantitative yield. Synthetically this protocol would have much precedence than other procedures since it is more facial and convenient method involving such a biological waste material of discarded mussel shell. The, final products were characterized by X-Ray Diffraction Spectroscopy (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Field Emission Scanning Electron Microscopy (FE-SEM), The Energy Dispersive Analysis of X-rays (EDAX), and Field Emission Transmission Electron Microscopy (FE-TEM) analysis.
