Use of synthetic polymers for biomedical application

Area of Science:

• Biomaterials Science
• Polymer Chemistry
• Biomedical Engineering

Background:

• Synthetic polymers are widely used in biomedical and pharmacologic applications, including prosthetic implants, sutures, and drug delivery systems.
• The long-term efficacy of these polymer-based devices is often unpredictable due to their exposure to harsh physiological environments.
• Biocompatibility is a critical factor influenced by the physical, chemical, and structural characteristics of polymers, encompassing both surface and bulk properties.

Purpose of the Study:
