• Abstract:

  The search for innovative biomaterials is intense in regenerative medicine and materials engineering. Polyhydroxyalkanoate (PHA) has stood out as a class of biodegradable polyesters produced by bacteria for energy storage. These polymers are highly valued for their biocompatible and biodegradable properties, making them ideal for medical devices, tissue engineering and controlled drug release. Applications include sutures, stents and scaffolds. 
  The importance of PHAs as biomaterials lies in their sustainability and functionality, being an ecological alternative to synthetic polymers. Its biocompatibility and biodegradability avoid the need for additional surgeries to remove the implanted material and reduce the risk of rejection or chronic infection. PHAs have the potential to improve patients' quality of life and minimize environmental impacts.
