Claim Text:
1. Method for producing a micro-nano combined active system in which nanoparticles of a first component are bonded to microparticles of a second component, comprising: producing a low-ligand colloidal suspension containing nanoparticles of the first component by ablating a substrate containing the first component with a laser beam while the substrate is positioned in a liquid such that first component of the substrate vaporized by the laser beam immediately solidifies in the liquid to form the nanoparticles in the colloidal suspension; adding microparticles to the colloidal suspension containing the nanoparticles or adding the colloidal suspension containing the nanoparticles to a dispersion containing the microparticles and homogeneously dispersing the microparticles so that the nanoparticles adsorb onto the microparticles; and separating the microparticles and the nanoparticles bonded thereto from the liquid and drying the microparticles and the nanoparticles bonded thereto to form the micro-nano combined active system.
