Abstract

The invention concerns a nanofiber structure with immobilized organic agens that consists of silica nanofibers whose surface was modified with aminoaikyialkoxysilane and of subsequently immobilized organic agens. The invention also concerns a method of preparation of the nanofiber structure with immobilized organic agens, while silica nanofibers are prepared by electrostatic spinning from the initial sol synthesized by a sol-gel method from tetraalkoxysilane, heat-treated and their the surface modified by a solution of aminoaikyialkoxysilane and organic agens is then immobilized on the modified surface of the nanofibers.
