Green synthesis and antibacterial activity of hydroxyapatite nanorods for orthopedic applications

Abstract

Abstract

Microwave assisted green synthesis of Hydroxyapatite nanorods using Moringa oleifera flower extract and its antimicrobial applications

“…Parameters like structure, size and elemental composition are important besides the quantum size effects in materials for nanometer scale for their promising applications. The bone substitutes should be prepared for individual patients with all details controlled on the micrometer level [1]. The main mineral constituent of bone is calcium.…”

Experimental studies on caffeine mediated synthesis of hydroxyapatite nanorods and their characterization

“…Green synthesis of HA got extensive scope because of its eco-friendly. Reducing, capping and stabilizing properties of many plant extracts such as Moringa oleifera leaf, gum-arabic, grape seed, banana, tamarind extract, Coccinia grandis and Azadirachta indica, orange, and potato peel, papaya leaf and calendula flower [10][11][12][13][14][15][16]. When an aqueous plant extract is used a green reducing agent during the synthesis of metal or metal oxide nanoparticles, explaining the role of a particular phytochemical is not an easy one.…”

Preparation of Calcium Phosphate Nanoparticles: Study their Characterization and Antibacterial Activity

“…Peaks of the phosphate group were comparable with peaks at 1,020, 600, and 560 cm -1 , introduced by Kojima and his group in 2018. 16 The presence of the above functional group, hydroxyl group, and phosphate group, show the formation of CPNPs in the HAP phase according to Kojima S. 17 The observed peak at 1,521.83 cm -1 corresponding to the carbonate group is due to the absorption of CO 2 from the atmosphere. 18 On the contrary, the peaks at 1,645.49, 1,725.22, and 3,383.75 cm -1 are attributed to water molecules due to the water adsorption during the synthesis process.…”
