Nanomedicine is a field of science that uses nanoscale materials for the diagnosis and treatment of human disease. It has emerged as an important aspect of the therapeutics, but at the same time, also raises concerns regarding the safety of the nanomaterials involved. Recent applications of functionalized biodegradable nanomaterials have significantly improved the safety profile of nanomedicine.
Our goal is to evaluate different types of biodegradable nanomaterials that have been functionalized for their biomedical applications.
In this review, we used PubMed as our literature source and selected recently published studies on biodegradable nanomaterials and their applications in nanomedicine.
We found that biodegradable polymers are commonly functionalized for various purposes. Their property of being naturally degraded under biological conditions allows these biodegradable nanomaterials to be used for many biomedical purposes, including bio-imaging, targeted drug delivery, implantation and tissue engineering. The degradability of these nanoparticles can be utilized to control cargo release, by allowing efficient degradation of the nanomaterials at the target site while maintaining nanoparticle integrity at off-target sites.
While each biodegradable nanomaterial has its advantages and disadvantages, with careful design and functionalization, biodegradable nanoparticles hold great future in nanomedicine.
纳米医学是一个利用纳米级材料进行人类疾病诊断和治疗的科学领域。它已成为治疗学的一个重要方面,但同时也引发了对所涉及纳米材料安全性的担忧。功能化可生物降解纳米材料的最新应用显著改善了纳米医学的安全性。
我们的目标是评估已针对其生物医学应用进行功能化的不同类型的可生物降解纳米材料。
在本综述中,我们以PubMed作为文献来源,选择了最近发表的关于可生物降解纳米材料及其在纳米医学中应用的研究。
我们发现可生物降解聚合物通常因各种目的而被功能化。它们在生物条件下自然降解的特性使这些可生物降解纳米材料可用于许多生物医学目的,包括生物成像、靶向药物递送、植入和组织工程。这些纳米颗粒的可降解性可用于控制货物释放,通过使纳米材料在靶位点有效降解,同时在非靶位点保持纳米颗粒的完整性。
虽然每种可生物降解纳米材料都有其优缺点,但通过精心设计和功能化,可生物降解纳米颗粒在纳米医学中具有广阔的前景。
