Biocompatible fibers from fungal and shrimp chitosans for suture application

• Fungal and shrimp chitosan were wet spun to monofilament yarns. Using adipic acid as solvent generally resulted in fibers with higher tensile strength compared obtained using lactic acid. Chitosan monofilaments showed a similar or better biocompatibility commercial sutures. are good candidates for being used Purified fungal crustacean by acids solvent. The lowest viscosity at which fiber formation was possible 0.5 Pa·s; below this value, aggregates from low molecular weight (32 kDa) formed, could not be collected dried. Fiber achieved high (400 (406.7 chitosans well (50–190 kDa). Fibers made of the exhibited strength; highest observed Young’s modulus 308.0±18.4 MPa 22.7±4.0 GPa, respectively. SEM images indicated cylindrical fibers. survival (viability) human skin fibroblasts presence different measured tetrazolium-based colorimetric assay results confirmed that have than common conventional sutures, regardless type. Accordingly, sources serve application
