*Titulo: Non-affine viscoelastic response of semiflexible networks

*Resumo: From the theoretical and computational point of view, methods to evaluate the mechanical response of semiflexible filaments networks are known since almost two decades [1,2]. However, only now those methods were extended to describe the full viscoelastic response of networks and were applied in the study of the formation of the peptide gels [3,4]. In contrast to the usual approaches, which are based on continous/effective descriptions of the elastic media and are limited to length scales much larger than the their smallest structures (e.g., proteins or peptides), our mesoscopic/multi-scale approach [3,5] provide a novel approach that might lead to new theoretical and computational developments for the characterization of the microrheology of gel-like semisolids materials.
