The development of biodegradable nanocarriers has long been a priority for researchers and medical professionals in the realm of drug delivery. Because of their inherent benefits, which include superior biocompatibility, customizable degradability, easy surface functionalization, and stealth-like behavior, polylactic acid-hyperbranched polyglycerol (PLA-HPG) copolymers have demonstrated a promising future in the field of biomedical research. The synthesis of PLA-HPG copolymers and the creation of their nanoparticles for biomedical uses have been the focus of current efforts. In this review, we summarize the synthetic strategies of PLA-HPG copolymers and corresponding nanoparticles, and highlight their physicochemical properties, biocompatibility, and degradation properties. Furthermore, we introduce a number of PLA-HPG nanoparticles that are utilized for surface skin delivery, wound dressing, and in vivo drug delivery biological applications. Finally, we conclude by offering our thoughts on how this nanoplatform might advance in the future.
长期以来,可生物降解纳米载体的研发一直是药物递送领域研究人员和医学专业人士的重点。聚乳酸-超支化聚甘油(PLA-HPG)共聚物因其具有优异的生物相容性、可定制的降解性、易于进行表面功能化以及类似隐形的特性等固有优势,在生物医学研究领域展现出了广阔的前景。目前的工作重点是PLA-HPG共聚物的合成及其用于生物医学用途的纳米颗粒的制备。在这篇综述中,我们总结了PLA-HPG共聚物及相应纳米颗粒的合成策略,并重点介绍了它们的物理化学性质、生物相容性和降解特性。此外,我们还介绍了一些用于皮肤表面给药、伤口敷料和体内药物递送等生物应用的PLA-HPG纳米颗粒。最后,我们对这个纳米平台未来可能的发展方向提出了自己的看法。
