  • Title: Specific molecular interactions by force spectroscopy: from single bonds to collective properties.
    Author: Lévy R, Maaloum M.
    Journal: Biophys Chem; 2005 Oct 03; 117(3):233-7. PubMed ID: 15963626.
    Abstract:
    Interactions involving multiple bonds occur throughout biology, and have distinct properties that are fundamentally different from those present in single bond systems. We have developed a new method to analyse the AFM force measurements in order to extract relevant information and to characterise the interactions involving from single to multiple bonds. Our study reveals a surprising behaviour in the presence of multiple bonds with a high rebinding probability: the mean binding forces increase with decreasing pulling velocity. Such behaviour is different from the force dependence on the loading rate for single bond rupture or existing models for multiple bonds rupture.
