VERSATILE AND SENSITIVE BIOSENSOR

摘要

Contemplated methods and devices comprise use of a charged probe and a pseudoligand in the electrochemical detection of a wide range of analytes, including nucleic acids, proteins and small molecules. In certain embodiments, the pseudoligand forms a complex with the probe that has a reduced charge magnitude compared to the probe itself, and is displaced from the probe when the complex is exposed to the analyte.
