• feedstock solution and winding the emerging fiber around a rotating magnetic collector needle upon coagulation. In summary, our helical chitosan microfibers are very attractive for future use in magnetic tissue engineering or for the development of biocompatible actuator systems. Keywords: biocompatible

A few examples are the structural motifs in proteins and DNA at the molecular level
