Query: Complexation of a polyelectrolyte with oppositely charged spherical
  macroions: Giant inversion of charge   Complexation of a long flexible polyelectrolyte (PE) molecule with oppositely
charged spherical particles such as colloids, micelles, or globular proteins in
a salty water solution is studied. PE binds spheres winding around them, while
spheres repel each other and form almost periodic necklace. If the total charge
of PE is larger than the total charge of spheres, repulsive correlations of PE
turns on a sphere lead to inversion of the net charge of each sphere. In the
opposite case, we predict another correlation effect: under-screened by PE
spheres bind to PE in such a great number that they invert charge of PE. The
inverted charge by absolute value can be larger than the bare charge of PE even
when screening by monovalent salt is weak. At larger concentrations of
monovalent salt, the inverted charge can reach giant proportions. Our theory is
in qualitative agreement with recent experiments on micelles-PE systems.
