Agarose is a polysaccharide extracted from the cell walls of marine red algae. In the hot solution state, agarose chains exist in a randomly coiled configuration. On cooling below around 40°C, the coils order to form helices which further aggregate into thick bundles called super helices resulting the formation of stable hydrogels. Despite their many advantageous properties, most hydrogels that are currently used in medical applications and tissue engineering easily fracture even under mild loading conditions due to their poor mechanical strength which originate from the solvent content within the network structure. The preparation of network structures stabilized with nano-sized fillers has been an effective approach to increase the mechanical strength of gels. In this study, we prepared agarose/FF-PNT hydrogels By controlling the preparation conditions, such as temperature, the amounts of FF and agarose. |
