Biocompatible polymers are gaining great interest in the field of biomedical applications. The term biocompatibility refers to the suitability of a polymer to body and body fluids exposure. Biocompatible polymers are both synthetic (man-made) and natural and aid in the close vicinity of a living system or work in intimacy with living cells. These are used to gauge, treat, boost, or substitute any tissue, organ or function of the body. A biocompatible polymer improves body functions without altering its normal functioning and triggering allergies or other side effects. It encompasses advances in tissue culture, tissue scaffolds, implantation, artificial grafts, wound fabrication, controlled drug delivery, bone filler material, etc.
This review provides an insight into the remarkable contribution made by some well-known biopolymers such as polylactic-co-glycolic acid, poly(ε-caprolactone) (PCL), polyLactic Acid, poly(3- hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), Chitosan and Cellulose in the therapeutic measure for many biomedical applications.
Various techniques and methods have made biopolymers more significant in the biomedical fields such as augmentation (replaced petroleum based polymers), film processing, injection modeling, blow molding techniques, controlled / implantable drug delivery devices, biological grafting, nano technology, tissue engineering etc.
The fore mentioned techniques and other advanced techniques have resulted in improved biocompatibility, nontoxicity, renewability, mild processing conditions, health condition, reduced immunological reactions and minimized side effects that would occur if synthetic polymers are used in a host cell.
Biopolymers have brought effective and attainable targets in pharmaceutics and therapeutics. There are huge numbers of biopolymers reported in the literature that has been used effectively and extensively.
生物相容性聚合物在生物医学应用领域引起了极大的兴趣。生物相容性一词是指聚合物与人体和体液接触的适宜性。生物相容性聚合物既有合成(人造)的,也有天然的,有助于在活系统的近距离内或与活细胞亲密接触。这些聚合物用于测量、治疗、增强或替代身体的任何组织、器官或功能。生物相容性聚合物可以改善身体功能,而不会改变其正常功能,也不会引发过敏或其他副作用。它涵盖了组织培养、组织支架、植入物、人工移植物、伤口制造、控制药物释放、骨填充材料等方面的进展。
本文综述了一些知名生物聚合物(如聚乳酸-共-羟基乙酸、聚(ε-己内酯)(PCL)、聚乳酸、聚(3-羟基丁酸-co-3-羟基戊酸)(PHBV)、壳聚糖和纤维素)在许多生物医学应用中的治疗措施方面的显著贡献。
各种技术和方法使生物聚合物在生物医学领域更加重要,例如增强(取代石油基聚合物)、薄膜加工、注塑成型、吹塑技术、控制/可植入药物输送装置、生物接枝、纳米技术、组织工程等。
上述技术和其他先进技术提高了生物相容性、低毒性、可再生性、温和的加工条件、健康状况、减少免疫反应和最小化副作用,如果在宿主细胞中使用合成聚合物,就会产生这些副作用。
生物聚合物在药剂学和治疗学方面带来了有效的、可实现的目标。文献中有大量的生物聚合物被报道,并且已经被有效地广泛应用。
