Ceramic processing without firing, sintering and expensive equipment represents agrowing research field within materials science. With respect to the search of new synthesispathways living nature provides paradigms for procedures that occur at ambient conditions and byapparently simple means. In this connection, biomineralization yields highly complexorganic/inorganic structures, e. g. within nacre or bones. In general, the formation of thesebiominerals involves organic molecules that act as templates during the mineralization of inorganicphases.Bio-inspired ceramic synthesis aims to imitate such principles by technical means. Accordingly,these routes consider the template-induced formation and the structural design of ceramics fromsolutions of suitable metal salts. This paper describes such routes by means of the preparation ofceramics like titania, vanadia, and zinc oxide. The influence of (bio)organic molecules (e. g.polyelectrolytes, self-assembled monolayers, amino acids, peptides and proteins) on the micro- andnanostructure formation and on the evolution of the morphology of these solids will be discussed.Furthermore, mechanical as well as functional properties of the obtained architectures are treated
