Abstract :Layered Double Hydroxides based nanoparticles offer significant advantages in biological applications with high biocompatibility and low cytotoxicity. In this study, nanoparticles (nMg/Al-NO3-LDH) were synthesized by the co-precipitation method and synthesis optimization of the nanoparticles was carried out by hydrothermal treatment. The effect of hydrothermal treatment on Z-average and surface charge was evaluated. Experiments were performed at 80˚C and 100˚C during in the range of 2-48 h by using different stirring rates (250, 1000, and 1500 rpm) and without stirring. Dynamic Light Scattering (DLS) was used to assess the particle size (nm), polydispersity index (PDI), and zeta potential (mV) of the nanoparticles. The chemical structure of nanoparticles was characterized by Fourier Transform Infrared spectrometry (FTIR). As a result, nanoparticles with an optimum particle size of 86.87 nm, a PDI of 0.132 and a zeta potential (mV) of 44.4±8.74 were obtained at 80˚C, 48h and 250 rpm. The data showed that Mg/Al-NO3-LDH nanoparticles have suitable physical properties for biological applications.
