Nano/microgels are colloidal spherical particles consisting of polymer network. These particles show a fascinating swelling response to external stimuli and therefore are very promising materials in food industry and medicine including drug delivery applications. Due to advances in microgel synthesis, resulting polymer network of nano/microgels can be of different topologies: homogeneous and core-shell topologies. We developed computational coarse-grained models for studying nano/microgels of both topologies. The models are aimed at reproducing microgels synthesized inside a droplet. The main feature of these models is that the resulting polymer network has a random mesh size and its topology depends on the size of the confining sphere where the crosslinking process takes place. We study the structural and swelling properties of the modeled nano/microgels under different solvent conditions. We also include electrostatic interactions to reveal how their influence on the microgel properties.
