Description
Highlights
Highly dispersed Ag NP were synthesized and anchored on eggshell particles by ball milling.
The antimicrobial activity of the eggshell/Ag nanocomposite and pristine Ag NPs were compared.
The eggshell/Ag nanocomposite showed superior antimicrobial properties.
The hydrophilic groups of the protein in eggshell promoted the dispersion in aqueous solution.
Abstract
Biobased calcium carbonate and silver hybrid nanoparticles were synthesized using a simple mechanochemical milling technique. The XRD spectrum showed that the hybrid materials is composed of crystalline calcite and silver nanoparticles. The TEM results indicated that the silver nanoparticles are discrete, uncapped and well stabilized in the surface of the eggshell derived calcium carbonate particles. The silver nanoparticles are spherical in shape and 5–20 nm in size. The SEM studies indicated that the eggshells are in micron size with the silver nanoparticle embedded in their surface. The hybrid eggshell/silver nanocomposite exhibited superior inhibition of E. coli growth using the Kirby–Bauer discs diffusion assay and comparing the zone of inhibition around the filter paper disc impregnated with the hybrid particles against pristine silver nanoparticles.
