Osseointegration of metallic implants used in orthopedic surgery requires that osteoprogenitor cells attach and adhere to the surface, then proliferate, differentiate into osteoblasts, and finally produce mineralized matrix. Because the ability of progenitor cells to attach to a scaffold surface

Polyelectrolyte (PE) multilayer (PEM) thin films prepared by layer-by-layer self-assembly on flexible substrates are exposed to elongation in many fields of technology. Upon elongation, these types of films are showing interesting, but not understood, phenomena, such as controlled wetting, stimuli-responsive

Polyelectrolyte multilayers (PEMs) deposited on flexible supports are promising candidates for many applications ranging from controlled wettability over stimuli responsive nanovalves to lithography free surface structuring. Since many potential applications involve elongation of these films, we investigated the effect of
