Abstract in brief

Electrostatic interactions are crucial for the assembly of single-stranded RNA viruses, requiring the viral proteins and genetic material to have opposite charges for proper formation.
The study uses polymer physics and statistical mechanics to analyze how synthetic virus capsids encapsulate polyelectrolyte molecules, finding that factors like surface charge density, capsid size, and polymer charge influence the amount of material inside, but not salt concentration.
Unlike natural viruses, synthetic ones are predicted not to experience osmotic swelling pressures, and their assembly is linked to the capsid surface charge being above a certain threshold that allows polymer adsorption and proper encapsulation.]
