Abstract
Abstract
The present research is characterized by ecofriendly, low cost and robust methods to synthesize calcium hydroxide (CH) nanoparticles using clove oil as capping and reducing agent and nonionic block copolymers as surface modifiers and particle size reducers. The prepared nanoparticles were characterized using UV–visible spectroscopy, dynamic laser light scattering, X-ray diffraction, Fourier transform infra-red spectroscopy, energy dispersive X-ray spectroscopy and transmission electron microscopy. The average effective diameter and crystallite size of particle calculated from DLS and XRD were 97–178 and 22–36 nm respectively. The synthesized NPs showed excellent catalytic activities against Allura red and Fast green dye. They also showed improved anti-bacterial and antifungal activities against Staphylococcus aureus, Klebsiella pneumonia and Candida albicans with minimum inhibitory concentration of 50 μl ml−1. The prepared nanocrystals were also incorporated into gum Arabic to be used as consolidant for archaeological bone fragments to fill the cracks, reinforce their mechanical features and save them from further decay. The SEM images of all the bone fragments before and after treatment clearly specify the effectiveness of this treatment.
