Facile synthesis of hydroxyapatite nanoparticles from eggshell biowaste using<i>Azadirachta indica</i>extract as a green template

Abstract

Hydroxyapatite nanoparticles (HANPs) were successfully synthesized from eggshell waste by microwave-assisted (MW) as well as conventional heating precipitation methods and a green template i.e. , Azadirachta indica (AI) (neem) leaf extract.
