Аннотация:Silicon nanoparticles decorated with small gold (Au) inclusions are of potential interest as agentsfor efficient photothermal conversion in tumor hyperthermia applications. In this work, we present the technologyfor synthesizing a suspension of composite silicon–gold (Si/Au) nanoparticles with a core-satellitetype morphology. They are quasi-spherical with the mean diameter of up to 75 nm and relative size dispersionnot exceeding 32%, while the decorating Au inclusions range in size of 5–15 nm. Fabrication is implementedthrough a dual-stage laser ablation technique employing a porous silicon target, ethanol (first stage) and awater-ethanol solution with chloroauric acid HAuCl4 (second stage) as buffer media. The fabricated compositeSi/Au nanoparticles possess a high degree of crystallinity and exhibit moderate colloidal stability in water.
