Preparation of hybrid particles of Ag nanoparticles and eggshell calcium carbonate and their antimicrobial efficiency against beef-extracted bacteria.

In this study, hybrid particles of AgNPs-loaded eggshell calcium carbonate (AgNPs/eCaCO) were prepared by co-precipitating the eggshell in the presence of freshly prepared AgNPs with a particle size of 10-30 nm. The hybrid particles were comparatively precipitated at 25°C and 35°C using poly (sodium 4-styrenesulfonate) as a polyelectrolyte. The AgNPs/eCaCO particles prepared at 25°C had a spherical morphology with a mean diameter of 3.
