Design of Intelligent Polymer of Gelatin-Pnipaam under Gamma Radiation for Cellular Applications
Author(s):
Abstract:
Thermo-sensitive polymers were prepared by graft copolymerization of gelatin with N-Isopropylacrylamide via gamma radiation. Characterization of polymers such as DSC analysis, swelling in different ratios and cell assays were investigated. DSC and solubility analysis showed gelatin and NIPAAm monomer were grafted via gamma radiation successfully. Results show swelling of samples increased with to gelatin increasing. Swelling ratio and curves results administrated hydrophilicity / hydrophobicity of hydrogel that this property is due to presence of PNIPAAm in different temperatures. The polymer was tested for harvesting epithelial cells after carrying out cell culture at 37 °C and incubating the confluent cells at 10°C for spontaneous detachment of cell sheet from polymer surface without enzyme treatment. These unique properties of the hydrogel would make it a promising support for drug delivery systems and tissue regeneration.
