  The article describes fabrication and properties of composite fibrous
scaffolds obtained by electrospinning of the solution of
poly({\epsilon}-caprolactone) and arginine in common solvent. The influence of
arginine content on structure, mechanical, surface and biological properties of
the scaffolds was investigated. It was found that with an increase of arginine
concentration diameter of the scaffold fibers was reduced, which was
accompanied by an increase of scaffold strength and Young modulus. It was
demonstrated that porosity and water contact angle of the scaffold are
independent from arginine content. The best cell adhesion and viability was
shown on scaffolds with arginine concentration from 0.5 to 1 % wt.
