ResumoWhen nanoparticles get into a living body, they interact with body fluids. This study shows high physicochemical persistence of electroexplosive aluminum nanoparticles in physiological solutions simulating body fluids: Artificial Sweat (ASw), Simulated Saliva (SS), Simulated Gastric Fluid (SGF), and Artificial Alveolar Fluid (AAF). It has been demonstrated that after 14 days of exposure in ASw SS SGF AAF solutions, the average size of initial 90 nm nanoparticles became 90 100 230 90 nm, and the average size of initial 5 μm agglomerates became 1.6 0.9 1.0 3.0 μm, respectively. According to s SEM data, the exposed particles retained their spherical shape. With the help of the X-ray phase analysis it was shown that the oxide/hydroxide phase content in nanoparticles did not increase. It has been concluded that highly-reactive aluminum nanoparticles are capable to retain their phase composition, dispersion, and morphology in synthetic body fluids.
