“…The chargedipole interactions between negatively-charged PEG-PLA molecules and positively-charged Tat-EGFP may have contributed to morphology changes. At a fixed polymer concentration, a higher protein concentration may result in a higher population of oppositely charged molecules that may increase coagulation and particle formation rate resulting in smaller particles (e.g., MP-3 vs. MP-1 and MP-4 vs. MP-2) whereas like-charged molecules may inhibit or decrease the coagulation and particle formation process [28,29].…”

This paper investigates the interaction of two dust particles in non-equilibrium plasma at elevated pressures. On the basis of asymptotic shielding theory resulting in two-exponential shielding the electrostatic energy of two charged fine particles is determined. The electrostatic energy dependence on interparticle distance proves to have a minimum as in an equilibrium plasma. The electrostatic interaction force of the particles is calculated. This force is proved to be non-symmetric: for different charges the force acting on one dust particle was not equal to the force acting on the other dust particle. This is due to non-symmetric charge separation in the vicinity of different charged dust particles. It is stated that likely charged particles repel each other and at the closest approach the attraction is only possible. Relationships to determine the modified nonideality parameter for the interaction potential, which consisted of two exponents with different shielding lengths, were obtained.

“…Most of these have looked at the coagulation of a monodisperse size population, given that coagulation due to Brownian motion tends to form cluster of similar size [23]. 0093-3813/04$20.00 © 2004 IEEE Only a few groups have examined the effects of particle charge on coagulation [11], [14], [17], [22].…”

“…Many of these employ statistical techniques to solve the coagulation equation [11], [14], [22]. However, the complexity of the problem has shown that it is advantageous to use a self-consistent -body approach to fully model and understand the processes involved [12], [23].…”

A numerical model with broad applications to complex (dusty) plasmas is presented. The self-consistent -body code allows simulation of the coagulation of fractal aggregates, including the charge-dipole interaction of the clusters due to the spatial arrangement of charge on the aggregate. It is shown that not only does a population of oppositely charged particles increase the coagulation rate, the inclusion of the charge-dipole interaction of the aggregates as well as the electric dipole potential of the dust ensemble decreases the gelation time by a factor of up to 20. It is further shown that these interactions can also stimulate the onset of gelation, or "runaway growth," even in a population of particles charged to a monopotential where previously it was believed that like-charged grains would inhibit coagulation. Gelation is observed to occur due to the formation of high-mass aggregates with fractal dimensions greater than two, which act as seeds for runaway growth.
