Abstract: A method for producing a nanofiber-based product includes providing a carrier material solution having a carrier material, and bringing the carrier material in contact with a collector by electrospinning. The carrier material essentially consists of a polymer being—at least after having contacted the collector—embedded in a polymer, which polymer is formed by a crosslinker of the general formula (I) wherein R1 is a single bond between the adjacent carbon atoms, or a carbohydrate chain having 1 to 10 carbon atoms and optionally bearing a hydroxy group, and wherein R2, R3, R4 and R5 are independently from each other a hydrogen; a carbohydrate chain having 1 to 10 carbon atoms and optionally bearing a hydroxy group; a hydroxy group; or a sulfhydryl group; with the provision that the compound bears at least two hydroxy groups, or two sulfhydryl groups, or one hydroxy group and one sulfhydryl group.
