20160136332 | THREE-DIMENSIONAL POROUS STRUCTURE MADE OF NANOFIBRE WEB FRAGMENTS AND METHODS FOR PRODUCTION THEREOF - A three-dimensional, porous structure made of fragments of a nanofibre web is provided. Furthermore, a method for the production of a three-dimensional, porous structure made of nanofibre web fragments is proposed. The three-dimensional, porous structure is used for example in medicine, preferably in regenerative medicine. Furthermore, the structure according to the invention made of fragments of a nanofibre web can be used for the treatment of tissue damage, for the immobilisation of biological cells, for the construction of biological tissue and as a biological filler in vitro and also in vivo. | 05-19-2016 |
