Polymers, grafted bioactivity

In designing nanofiber mat constructs for specific applications, the engineering as well as surface-chemistry requirements cannot sometimes be satisfied by a single material. For instance, an application may need good nanofibers of magnetic susceptibility as well as enzyme activity via surface-grafted bioactive moieties. In such instances composite mats made of either layered or mixed nanofibers of two or more different polymers might be employed. [Pg.274]

After an extensive review of possible new materials, the team found a material that had a surface-to-volume ratio closer to 1000 M /M and a void volume up to 98%. A hydrophilic coating could be grafted to its surface to provide a reservoir capacity to release nutrients in a controlled manner. Lastly, the hydrophilic coating could be copolymerized with certain bioactive polymers and ligands that improve cell adhesion dramatically. [Pg.30]

Wang [3] prepared the amphiphilic biocompatible cyclodextrin graft polymer, poly(ethylene glycol-g-cyclodextrin), (III), containing modified cyclodextrin which was used as a bioactive drug delivery agent. [Pg.47]
