Abstract
The increased prominence in the use of nanoparticles has made it important to employ synergy between nanoparticles while harnessing individual metallic and biological properties to improve and modify the surface, the versatility, and efficiency of nanoparticle hybrid. This study aims to conduct a bio-assessment assay of nanoparticle hybrid systems within an in-vitro set-up and improve the surface modifications of these systems. The hybrid surfaces are characterized using a scanning electron microscope, dynamic light scattering (DLS), X-ray diffraction analysis (XRD), and Fourier-transform infrared spectroscopy (FTIR). FTIR reveals the presence of functional groups like phenols, carboxylic acids, and esters. The XRD confirms the hexagonal crystalline phase of Fe-NZnO, the cubic lattice of Fe-NCaO, and the rutile phase of TiO2. The hydrodynamic diameter of Fe-NZnO-NCaO, Fe-NTiO2-NCaO, and Fe-NTiO2-NZnO are shown to be 163.2, 164.6, and 219.4 nm, respectively, using DLS analysis. Turbidity analysis indicates that Fe-NZnO-NCaO is the least aggregated particle following a 14-day observation period, meaning that it is the most stable over that period. Anti-hemolytic erythrocyte assay demonstrates the relative biocompatibility and ability of the hybrids to enhance cell protein protection. Fe-NZnO-NCaO and Fe-NTiO2-NCaO exhibit higher post-treatment cytotoxicity across the concentrations than Fe-NTiO2-NZnO.
