Aliphatic copolyesters have garnered significant interest in the biomedical field owing to their biodegradable and biocompatible nature. The development of these polymers has emerged as a promising alternative to conventional synthetic materials for biomedical applications. In this study, the author B Kalpana reports on the synthesis and characterization of aliphatic copolyesters using 1,4-dithiane-2,5-diol as a co-monomer for biomedical applications. The synthesis process of aliphatic copolyesters involved the use of a combination of hydrophobic and hydrophilic monomers, resulting in the production of copolymers that exhibit amphiphilic properties. The synthesized copolymers were characterized for their chemical and physical properties using a range of analytical techniques, including spectroscopic analysis (NMR, IR, MS), gel permeation chromatography (GPC), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), rheology, and surface properties. The copolyesters' mechanical and thermal properties were also evaluated, and the results indicated that they have excellent mechanical properties and thermal stability suitable for biomedical applications. The aliphatic copolyesters' biocompatibility was assessed through in vitro and in vivo experiments using various cell lines and animal models, respectively. The copolymers showed excellent biocompatibility, low cytotoxicity, and hemocompatibility. Furthermore, they exhibited good biodegradability, controlled drug release, and antibacterial properties, making them suitable for drug delivery, tissue engineering, wound healing, and implant applications. The copolyesters' biomineralization properties were also investigated, and the results showed that they promote cell adhesion and bone regeneration, making them ideal for bone tissue engineering. The author further discusses the regulatory affairs and patentability of aliphatic copolyesters for biomedical applications. The biocompatibility testing and clinical trials required for regulatory approval are also discussed, and the author emphasizes the importance of understanding the host response to these materials to ensure their safe use in clinical applications. Overall, this study demonstrates that aliphatic copolyesters synthesized using 1,4-dithiane-2,5-diol are promising materials for biomedical applications due to their biodegradability, biocompatibility, and excellent physical and mechanical properties. The results of this study pave the way for the development of innovative aliphatic copolyesters with superior properties and potential applications in the field of regenerative medicine.
