The mechanical response depended on the number of deposited layers and was explained semi-quantitatively with a fully atomistic model, where the LbL film was represented as superposing layers of hexagonal graphene-like atomic arrangements deposited on a stiffer substrate. The bending with no direct current or voltage being applied to a supramolecular structure containing biocompatible and antimicrobial materials represents a proof-of-principle experiment that is promising for tissue engineering applications in biomedicine.12953-12969engmagnetic nanoparticlesnatural rubber latexcarboxymethyl-chitosanlayer-by-layer assemblymolecular dynamicsArtigo10.3390/ijms140712953WOS:000322171700003Acesso abertoWOS000322171700003.pdf
