Abstract:
Protein-based polymers are some of the most promising candidates for a new generation
of innovative biomaterials as recent advances in genetic-engineering and biotechnological
techniques mean that protein-based biomaterials can be designed and constructed with
a higher degree of complexity and accuracy. Moreover, their sequences, which are derived
from structural protein-based modules, can easily be modified to include bioactive motifs that
improve their functions and material-host interactions, thereby satisfying fundamental biological
requirements.
The accuracy with which these advanced polypeptides can be produced, and their versatility,
self-assembly behavior, stimuli-responsiveness and biocompatibility, means that they have
attracted increasing attention for use in biomedical applications such as cell culture, tissue engineering,
protein purification, surface engineering and controlled drug delivery.
The biopolymers discussed in this review are elastin-derived protein-based polymers which
are biologically inspired and biomimetic materials. This review will also focus on the design,
synthesis and characterization of these genetically encoded polymers and their potential utility
for controlled drug and gene delivery, as well as in tissue engineering and regenerative medicine.
