Synthesis of coatings on simulated body fluid in presence of Ag nanoparticles on NiTi archwires

Abstract

In this study, coatings were synthesized on simulated body fluid (SBF) in the presence of silver nanoparticles on the surface of nickel-titanium archwires. The coatings were characterized using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray energy dispersive analysis (EDS), fast Fourier transform (FFT), force spectral density (PSD) analysis, surface geometry analysis and particle distribution analysis. The results show the efficiency of the electrostatic interaction of the SBF substrate and Ag nanoparticles in the formation of the coatings. The Ag nanoparticles in the coatings had diameters of approximately 50–150 nm. The pH and temperature conditions within the solution were optimized using a static technique. The functionality of the coatings and their relationship with the dominant wavelength in the force spectral density (PSD) and fast Fourier transform (FFT) analyses; were analyzed. This method opens up a new route for the synthesis of coatings in various body fluids using other biocompatible materials.
