The object of the present invention is a method for the production of block polymers comprising a firstand a second block comprising the method steps: A) providing a first block having a nucleophilic peptide sequence for afirst transpeptidase enzyme, B) providing a second block having a peptide recognition sequence for the first transpeptidase enzyme, C) linking the first block to the second block by means of the first transpeptidase enzyme, wherein the first and second blocks are independently selected from nanoparticles, non-peptide polymers, and recombinant proteins. Such a production method makes it possible to build block polymers from identical or different blocks in a particularly simple and controlled manner.
