Long-range interactions in adsorbed layers of virus particles

Abstract

The spatial distribution of adsorbed virus particles on a quartz surface was measured by electron microscopy. For low surface concentrations of adsorbed particles (around ${10}^8$ particles per squared centimeter) the distribution was found to deviate from a random distribution. The particles with a diameter of 54 nm were found to interact at distances up to 0.7 μm. These interactions showed up both in the pair distribution function g(r) and in the nearest-neighbor distance distribution.
