As a result, a hydrogel composite was created in a single-stage synthesis process. In addition, the applied methodology allowed us to avoid the need to use

Therefore, it can be concluded that there is a certain limit to the concentration of particles added to the hydrogel, which after the polymerisation process are trapped in the hydrogel skeleton. Above this limit, excess particles are still bound to the polymer

We observed that prostate cancer cells exhibit a strong migration ability by sensing changes in the extracellular environment through actin polymerization and filamentous pseudopods. This is because the role of actin polymerisation in cell adhesion structure formation

• that when we inhibit actin polymerisation with an actin-binding protein inhibitor, the actin fibrils fail to polymerise into bundles and the prostate cancer cells themselves have reduced elasticity values and increased viscosity values, thus reducing the migration ability of the prostate cancer cells

The second theory, although less popular, describes the stabilisation of polymers by molecules that results from the polymerisation of monomers which occur in the presence of nanoparticles. In this article, synthetic polymers were used as stabilisers

This polymerisation process was observed to induce morphological changes of the initially spherical vesicles towards irregular, asymmetric shapes

They also observed shape transitions in these model cells following actin polymerisation, but osmotic effects due to the addition of MgCl2
