Femtosecond laser synthesis of hybrid magnetic nanoparticles based on iron and gold with photothermal response

The paper presents the results of femtosecond laser ablation synthesis of magnetite nanoparticles, hybrid nanoparticles based on iron and gold in deionized water. The average size of the resulting hybrid nanoparticles was 60 nm with inclusions of gold nanoparticles no larger than 10 nm on the surface. The results of scanning electron microscopy of the obtained nanoparticles, optical density curves and dependences of photothermal activity of solutions under irradiation with continuous laser radiation at 805 nm are presented.
