Recent advances in biodegradable synthetic polymers focus on tailoring structures for tissue engineering and therapies. Injectable polymers show promise, though polyesters have limitations like acidic byproducts and processing challenges.

Area of Science:

  • Polymer Science
  • Biomaterials Engineering
  • Regenerative Medicine

Background:

  • Biodegradable synthetic polymers are crucial for advanced applications like tissue engineering.
  • Polyesters (polyglycolides, polylactides) are widely used but have drawbacks.
  • Emerging applications require tailored polymer structures for specific material needs.

Purpose of the Study:

  • To review recent developments in biodegradable synthetic polymers.
  • To discuss synthesis, properties, and biodegradability of various polymer classes.
  • To highlight polymers suitable for tissue engineered products and therapies.

Main Methods:

  • Literature review of studies from the past 10-15 years.
  • Discussion of major and new families of synthetic polymers.
