The problem of inhibiting viral DNA ejection from bacteriophages by multivalent counterions, specifically Mg(+2) counterions, is studied. Experimentally, it is known that MgSO(4) salt has a strong and nonmonotonic effect on the amount of DNA ejected. There exists an optimal concentration at which the minimum amount of DNA is ejected from the virus. At lower(More)
