Abstract
WE present here experimental evidence that adhesion of red cells to an oil–water interface is mediated by an attractive force acting at a distance apparently exceeding 100 nm. Although long-range forces have recently been measured between bilayer lipid lamellae in water1 and attraction between cells has been inferred from aggregation studies2,3, the long-range nature of attraction in cell studies has previously been an assumption rather than a deduction from experimental evidence. Our analysis strongly implicates a long range attractive force, but this force is extremely weak at large distances and whether it has any biological role in cell adhesion in physiological conditions is not known.
