Abstract EN
This paper reviews the advancements of a wide range of electrochemical aptamer-based biosensors, electrochemical aptasensors, for target analytes monitoring.
Methods for immobilizing aptamers onto an electrode surface are discussed.
Aptasensors are presented according to their detection strategies.
Many of these are simply electrochemical, aptamer-based equivalents of traditional immunochemical approaches, sandwich and competition assays employing electroactive signaling moieties.
Others, exploiting the unusual physical properties of aptamers, are signal-on (positive readout signal) and signal-off (negative readout signal) aptasensors based on target binding-induced conformational change of aptamers.
Aptamer label-free devices are also discussed.
