A highly sensitive microgravimetric lectin biosensor has been developed using carbohydrate-stabilized Au nanoparticles as a signal amplifier; mannose-stabilized Au nanoparticles formed a sandwich-type complex with the target Con A specifically bound to a mannose-modified Au QCM electrode to give an amplified frequency response.
