Surface Structure of Nanoporous Track Membranes for Biomedical Applications

Track membranes have attracted significant interest in the past two decades due to their numerous applications in the biological and medical experimental works. A particular feature of technology is the possibility of fabricating samples with predetermined number of pores. The present report describes the structural properties of surfaces track multi-pore membranes: different sizes of pores and different thicknesses of track membranes for methods of obtaining living biologically active substances, stem cells with conserved receptors and growth factors from adipose tissues, human blood on the basis of a combination of separation methods using nanoporous membranes. Track studies have shown that they have a complex structure. The greatest interest is that when processing membranes at a sufficiently high temperature (129-134 °C), the track slowly disappeared.
