Cellulose nanofibers were isolated from softwood pulp by mechanical fibrillation process and were utilized to develop biobased nanocomposites for biomedical application. Different processing techniques were attempted to develop nanocomposites for use as artificial ligament or tendon and the composites mechanical properties at room conditions as well as at simulated body condition (37 °C and 98 % RH) were studied. These initial studies indicated that the inherent properties like low toxicity, biocompatibility and biodegradability together with excellent mechanical properties of nanocelluloses makes cellulose based nanocomposites an excellent candidate for load bearing components in biomedical applications.
