Synthesis of Ternary Fe3O4/ZnO/Chitosan Magnetic Nanoparticles via an Ultrasound-Assisted Coprecipitation Process for Antibacterial Applications

Abstract: In this study, Fe3O4/ZnO/chitosan magnetic nanoparticles were synthesized by an ultrasound-assisted coprecipitation method. The magnetic nanoparticles were characterized by XRD, FT-IR, FESEM, and VSM techniques. The effects of ultrasonication time and content of chitosan on crystal size and lattice parameters of the nanoparticles were also studied via XRD spectra. FESEM measurements revealed that the coating consists of Fe3O4/ZnO nanoparticles of 15-20 nm in diameter homogeneously dispersed on the surface of c… Show more

“…Te coating material for magnetic nanoparticles must be compatible and maintain the stability of the magnetic nanoparticles [4][5][6]. Several coating materials for Fe 3 O 4 have been proposed, including polymers (such as dextran, albumin, polyethylene glycol, polyvinylpyrrolidone [7], folic acid [8,9], chitosan [10], and silica [11]).…”

“…Various methods have been widely used to synthesize Fe3O4/ZnO nanocomposites. It including hydrothermal [1], ultrasonication [17], coprecipitation [18], and sol-gel [19], sonochemical [20], and biosynthetic [21]. The ultrasonication method has not been carried out of the several methods mentioned.…”

“…The ultrasonication method is a method that utilizes high-frequency ultrasonic waves that are radiated into a solution so that it will cause collisions between particles to break large crystal aggregates into small crystal aggregates up to nanoscale. In addition, this method is effective, inexpensive, and environmentally friendly and requires a short time of experimentation [17]. Based on the results above, we researched to analyze Fe3O4/ZnO nanocomposites using ultrasonication.…”
