Abstract
The present invention relates to aptazyme sensor devices comprising, in addition to the aptamer, ribozyme and communication components, a competitive inhibitory component with a metal nanoparticle or a competitive inhibitory and signalling component with a metal nanoparticle and a label, such that the enzymatic activity of the ribozyme is inhibited as long as the inhibitory or the inhibitory and signalling component is bound to the substrate binding site of the ribozyme. The aptazyme sensor devices of the invention have increased shelf-life and are suitable for the parallel detection of different ligands by using an array of aptazyme sensor devices utilizing inhibitory and inhibitory and signalling components with different metal nanoparticles. The present invention furthermore relates to the post-synthetic chemical modification of the aptamer component for avoiding unspecific binding.
