  The surface hydrophobicity of poly($\epsilon$-caprolactone) electrospun
scaffolds prevents their interactions with cells and tissue integration. Plasma
treatment of the scaffolds enhances their hydrophilicity. However, the
hydrophobicity of scaffolds is restored in about 30 days. In this
communication, we report the possibility of polycaprolactone electrospun
scaffolds hydrophilization for more than 6 months. For that, diamond-like
coating was deposited on the scaffolds surface using pulsed vacuum arc
deposition technique in nitrogen atmosphere with sputtering of graphite target.
It was established that single-side modification preserving scaffold structure
is possible. The diamond-like coatings composition (sp2/sp3 hybridized carbon
ratio) was tunable with nitrogen pressure. In vitro tests with fibroblasts cell
culture did not reveal any cytotoxic compounds in the samples extracts.
