{Solutions|Options} of oppositely-charged polyelectrolytes and surfactants {have been|happen to be|have already been} {widely|extensively|broadly} studied {for a|to get a|for any} {variety of|number of|selection of} applications; they play {an important|an essential|a crucial|a vital} {role|function|part} {in the|within the|inside the} formulation of {personal|individual|private} care {products|goods|items|merchandise|solutions}, {can be|may be|could be|might be|is often|is usually} {used|utilized|employed|utilised|applied|made use of} as {an effective|an efficient} {strategy|technique|method|approach|tactic} for drug encapsulation, and serve as analogues to biological systems {such as|like|including|for example|for instance|which include} biomolecular condensates. Surfactant molecules self-assemble into micellar macroions {that are|which are|which can be|which might be|that happen to be} {known|recognized|identified} to {form|type|kind} complexes with oppositely-charged polyelectrolytes, {and can|and may} undergo a bulk liquid-liquid phase separation {known as|referred to as|called|generally known as} {complex|complicated} coacervation. This {process|procedure|method|approach|course of action} {results|outcomes|final results|benefits} {in a|inside a|within a} `coacervate’ phase {that is|that’s|which is|that is certainly|that is definitely|that may be} {rich|wealthy} in macroions, {and a|along with a|as well as a|plus a|and also a|in addition to a} `supernatant’ phase {that is|that’s|which is|that is certainly|that is definitely|that may be} dilute in macroions. {It is|It’s|It really is|It truly is|It can be|It is actually} {challenging|difficult} to model this phase separation {process|procedure|method|approach|course of action}, {due to|because of|as a result of|on account of|resulting from|as a consequence of} the disparate length scales and {strong|powerful|robust|sturdy} Coulombic interactions in these mixed macroion systems. {In this|Within this} {work|function|perform|operate}, we present a hybrid simulation and field theory model to describe polyelectrolytes/surfactants {solutions|options}, {where|exactly where} the surfactant species has self-assembled into worm-like micelle structures. We use self-consistent field theory (SCFT) to model the polyelectrolytes {in the|within the|inside the} {solution|answer|remedy|resolution|option} which interact {with the|using the|with all the|together with the} surfactant micelles. The surfactant micelle structures are determined by performing Monte Carlo (MC) simulations, {which are|that are} {used|utilized|employed|utilised|applied|made use of} to {determine|figure out|decide|establish|ascertain|identify} applied external fields {in the|within the|inside the} SCFT portion {of the|from the|in the|on the|with the|of your} model. We use these calculations to {determine|figure out|decide|establish|ascertain|identify} the {system|method|program|technique} {free|totally free|free of charge|cost-free|absolutely free|no cost} {energy|power} and map the phase diagrams for polyelectrolyte-surfactant coacervates, and subsequently {consider|think about|contemplate|take into account|look at|take into consideration} the {effect|impact} of {a number of|numerous|several|quite a few|a variety of|many} molecular parameters {such as|like|including|for example|for instance|which include} polyelectrolyte chain length, the volume {of the|from the|in the|on the|with the|of your} interacting micelle surface-sites, {and the|and also the|as well as the|along with the|plus the} electrostatic binding {energy|power} {between|in between|among|amongst|involving} the polyelectrolyte and micelle surface.
