Abstract

The invention relates to a method and to a device for producing conjugates comprising or consisting of a metallic nanoparticulate component and an organic component. Said method enables activated or reactive nanoparticles containing metal to be produced by irradiating a metal body with a laser beam and prevents the modification and damage of organic components of said conjugates by laser irradiation. Said nanoparticulate metallic component comprises plasmon resonant metal. According to the invention, the claimed method of production enables particles having a metal centre and a metal-oxide covering to be produced, in particular when using a carrier fluid containing oxygen, e.g. alcohol or water.
