ResumenColloidal solutions containing silica-coated silver nanoparticles (Ag@SiO2) were synthesized through a two-step process integrating physical and chemical mechanisms. In the first step, laser ablation of a silicon target submerged in deionized water generated an H2O-SiO2 colloid, termed the as-cast colloid. This contained nanometric SiO2 particles alongside micrometer-sized or larger silicon fragments produced by laser shockwave-induced target surface fragmentation. To refine particle size distribution and elevate nanometric SiO2 concentration, the as-cast colloid underwent secondary laser irradiation, effectively fragmenting larger particles. The second step involved adding ionic silver to both as-cast and irradiated colloids, yielding Ag@SiO2 nanoparticles. Structural properties were probed via XRD and TEM; optical characteristics via UV-Vis spectroscopy; and electrophoretic mobility via zeta potential measurements, both pre- and post-silver incorporation, to elucidate irradiation's influence on synthesis. For controlled agglomeration, AlCl3 was used to modify surface charge, neutralizing silanol groups on the silica shell and minimizing electrostatic repulsion through aluminum ion interactions. These findings demonstrate tunable Ag@SiO2 colloids with precise surface properties for future development of advanced nanomaterials suitable for microbicidal applications.es_ES
