Signal generating oligonucleotide-based biosensor

摘要

The present invention relates to oligonucleotide-based biosensors and a general method for their production and use. Specifically, the invention describes a novel signal-generating ligand complex comprising the combination of two or more aptamers linked together by a polymeric linker and further comprising a signaling system that provides a detectable signal upon binding of the signal-generating ligand complex to its target analyte.
