Synthesis of copper-silver doped hydroxyapatite via ultrasonic coupled sol-gel techniques: structural and antibacterial studies

Synthesis and characterizations of natural limestone-derived nano-hydroxyapatite (HAp): a comparison study of different metals doped HAps on antibacterial activity

“…The nding for Ag-HAp was consistent with the previous report. 24,27 The metallic Ag presence could be explained as the processing temperature is high, then Ag + ions migrate into bulk and reduced into Ag metal. 28 The fact of b-TCP is elaborated as follows.…”

“…22 Based on the above considerations, hydroxyapatite synthesis and characterization by utilizing earth-abundant limestone resources are highly critical. Although there are several reports on studying the synthesis and antibacterial activity of HAp [23][24][25] but in this report, we comprehensively synthesized and compared the effect of metal ions dopant on the antibacterial activity of HAp. To the best of our knowledge, no report compares antibacterial of HAp with different metal ions dopant using natural Sidikalang limestone as the calcium source.…”

A biodegradable silver oxide-treated hydroxyapatite nanoparticle (AgO@HA)-interlaced poly(etherimide)/poly(methylmethacrylate) membrane for blood purification: an in vitro study

“…The SAED pattern of the unique AgO@HA NPs shows distinguishable diffraction rings that correspond to the crystallographic planes (002) and (211). 45 The energy dispersive X-ray analysis (EDAX) of composite nanoparticles that include calcium, phosphate, silver, and oxygen is represented in Fig. 3(d).…”
