title: Self-assembly of rodlike receptors from bulk solution.
abstract: Optical waveguide lightmode spectroscopy has been used to observe the deposition of bacterial flagellar filaments of mean length 350 nm from bulk solution onto a smooth planar substratum, chemically modified to covalently bind the flagellar filaments on contact. At the highest practicable bulk concentration, the filaments follow the theoretically predicted kinetics of random sequential addition of highly elongated rigid rods to the substratum, but addition terminates with the rods almost perpendicular to the substratum. Rod-rod correlations in the bulk anomalously accelerate the rate of arrival of the filaments at the surface of the substratum, relative to spheres. At lower concentrations, this effect is absent, and the rods have time to order themselves on the substratum, forming a two-dimensional array.
