The goal of this work was to achieve proper chemical modification of poly‐ϵ‐caprolactone porous scaffolds by means of He/O2 Atmospheric Pressure Plasma‐Jet treatments with the aim of improving their affinity with cells. The surface chemical composition and wettability of plasma processed scaffolds was characterized, their cyto‐compatibility was tested with human Saos‐2 osteoblasts cells. Plasma‐grafted polar groups were found to improve the hydrophilicity of the scaffolds, which resulted in better clusterization and cytoskeleton morphology of cells cultured on them.
