The concept of synthetic multifunctional pores as substrate-independent optical signal transducers of chemical reactions is introduced with emphasis on the combination with substrate-specific signal generation in biomolecular transformations. Comparison with the general electrochemical transduction, known from conventional biosensors, and the general optical transduction of analyte-specific biomolecular recognition (rather than transformation), known from immunosensing, reveals the fundamental nature of the concept as well as an attractive complementarity to existing methods. Examples with transferases, hydrolases, lyases, and even an isomerase demonstrate that optical transduction with synthetic multifunctional pores is general far beyond the substrate-specific signal generators of electrochemical transduction, that is, the oxidoreductases, and absolutely unproblematic. In part very recent breakthroughs are used to highlight the remarkable promise of synthetic multifunctional pores as optical transducers of biomolecular transformation with regard to practical sensing and screening applications.
