  • Title: Biosensors for RNA aptamers-protein interaction.
    Author: Tombelli S, Minunni M, Mascini M.
    Journal: Methods Mol Biol; 2008; 419():109-19. PubMed ID: 18369978.
    Abstract:
    Aptamers are an alternative to antibodies in their role as biorecognition elements in analytical devices. RNA aptamers, specific for different proteins, have been exploited as biorecognition elements to develop specific biosensors (aptasensors). These recognition elements have been coupled to piezoelectric quartz crystals and surface plasmon resonance (SPR) devices as transducers. The procedure for fixing the aptamer onto these transducers and for monitoring the interaction with the target protein is shown here.
