The invention concerns a method and an apparatus for generation of micropartides containing an immobilized functional component, where the following measures are proposed: —spraying a liquid (32) containing a soluble alginate and a functional component consisting of molecules or nanoparticles to generate a stream (60) of droplets, —directing the stream (60) of droplets onto a precipitation bath (16) and capturing the droplets therein by application of high voltage (14), —precipitating the droplets in the precipitation bath (16) by means of a precipitation liquid (18) containing an alginate complexing agent, such that the droplets are solidified to form micropartides (10) containing the functional component and —extracting the micropartides (10) from the precipitation bath (16).
