Poly(ε-caprolactone) nanofibers were prepared by electrospinning giving rise to porous meshes. However, for some applications in tissue engineering where, for instance, cell migration into the inner regions of the mesh is aimed, the pore size obtained by conventional techniques is too narrow. To improve the pore size, laser irradiation with femtosecond pulses (i.e., negligible heat diffusion into the polymer material and confined excitation energy) is performed. A detailed study of the influence of the pulse energy, pulse length, and number of pulses on the topography of electrospun fiber meshes has been carried out, and the irradiated areas have been studied by scanning electron microscopy, contact angle measurements and spectroscopic techniques. The results show that using the optimal laser parameters, micropores are formed and the nature of the fibers is preserved. © 2010 Elsevier B.V.This work was partially supported by the European Integrated Project GENOSTEM (LSH-STREP-CT-2003-503161), the European Network of Excellence EXPERTISSUES (NMP3-CT-2004-500283), the Interreg III Project Proteus (SP1P151/03), Xunta de Galicia (Consolidación 2006/12) and Xunta de Galicia, Axudas para adquisición de instrumentación científica 2004, PGIDIT04PXI32201IF.
