Ligand-receptor interactions [PDF]

open access: yesReports on Progress in Physics, 1999
The formation and dissociation of specific noncovalent interactions between a variety of macromolecules play a crucial role in the function of biological systems. During the last few years, three main lines of research led to a dramatic improvement of our understanding of these important phenomena.
