  • Title: Thermodynamics of mechanical transduction of surface confined receptor/ligand reactions.
    Author: Bergese P, Oliviero G, Alessandri I, Depero LE.
    Journal: J Colloid Interface Sci; 2007 Dec 15; 316(2):1017-22. PubMed ID: 17889897.
    Abstract:
    Chemomechanics of surface stress is discussed in terms of interfacial thermodynamics. In the first section the paper shows how to quantitatively describe the chemical equilibrium of a receptor/ligand binding reaction confined at a solid-liquid interface and how the overall work of the reaction splits into chemical and surface work, that appears as a surface pressure. In the second section this thermodynamic model is applied to describe the experimental results of microcantilever bending induced by DNA hybridization occurring onto one of its faces.
