Summary of The Proposed Outcome.

Controlled delivery of PTH 1-34 peptide either systemic or oral using chitosan particles as a carrier will have high impact i.e. reduced time course and no painful for treating bone diseases such as osteoporosis and bone-related diseases such as breast cancer- and prostate cancer- induced bone metastasis or osteolysis.


In continuation of the ongoing research efforts at AIMS, Kochi, various marine based polymeric scaffolds were fabricated and combination of argon and nitrogen plasma treatment was carried out to improve its bio-responsiveness. The developed chitin/PHBV and chitin/PCL/ nCS scaffolds showed enhanced hydrophilicity, protein adsorption, cell attachment and proliferation. The addition of polar functional groups on the fibers by plasma treatment modified its property from hydrophobic to hydrophilic nature thereby increasing the applicability of this material. Protein adsorption was also enhanced. The developed membrane would prove beneficial for tendon tissue engineering after plasma treatment.
