Polymers in Regenerative Medicine

Biomedical applications of Polymers from Scaffolds to
Nanostructures

The ability of polymers to span wide ranges of mechanical
properties and morph into desired shapes makes them useful for a
variety of applications, including scaffolds, self-assembling
materials, and nanomedicines. With an interdisciplinary list of
subjects and contributors, this book overviews the biomedical
applications of polymers and focuses on the aspect of regenerative
medicine. Chapters also cover fundamentals, theories, and tools for
scientists to apply polymers in the following ways:

• Matrix protein interactions with synthetic surfaces

• Methods and materials for cell scaffolds

• Complex cell-materials microenvironments in bioreactors

• Polymer therapeutics as nano-sized medicines for tissue
  repair

• Functionalized mesoporous materials for controlled
  delivery

• Nucleic acid delivery nanocarriers

Concepts include macro and nano requirements for polymers as
well as future perspectives, trends, and challenges in the field.
From self-assembling peptides to self-curing systems, this book
presents the full therapeutic potential of novel polymeric systems
and topics that are in the leading edge of technology.
