BACKGROUND/AIM: The novel field of nanomaterials allows infinite possibilities in order to create antioxidant therapies. The present review is aimed to describe the state of art concerning on nanomaterials and their effects on reactive oxygen species (ROS) production. A wide range of nanoparticles has been designed for this purpose, and each one possesses some particular characteristics which allow these significant antioxidant results. Several in vivo and in vitro works state the ability of these nanoparticles to mimic the redox systems of the cells, and thus, the potential role of nanoparticles as antioxidant treatment for several diseases.
This paper was written after a review of the articles published on the field, using the "PubMed" and "Research Gate" databases.
The main types of nanoparticles are listed and explained below, offering a global vision of the field with great interest for research. Antitumor chemo- and radiotherapies have been found to improve efficacy by enhancing the selectivity of cytocidal effects and minimizing systemic adverse effects when such materials are used. Furthermore, catalytic nanomaterials can execute energy-free antioxidant cycles that scavenge the most harmful reactive oxygen species via SOD- and catalase-like activities.
This unique method is projected to result in significant gains in the long run. However, due to a lack of understanding of potential adverse body reactions to these novel strategies, caution must be exercised. Analyzing the biocompatibility of these nanomaterials carefully, particularly in terms of biokinetics and the problems that could arise from long-term retention of nonbiodegradable inorganic nanomaterials, is required.
背景/目的:纳米材料这一新兴领域为开发抗氧化疗法带来了无限可能。本综述旨在描述纳米材料及其对活性氧(ROS)产生影响的研究现状。为此已设计出多种纳米颗粒,每种都具有一些特定特性,从而产生了显著的抗氧化效果。多项体内和体外研究表明,这些纳米颗粒能够模拟细胞的氧化还原系统,因此纳米颗粒在多种疾病的抗氧化治疗中具有潜在作用。
本文是在查阅了该领域发表在“PubMed”和“Research Gate”数据库上的文章后撰写而成。
下面列出并解释了主要类型的纳米颗粒,展现了该领域的整体情况,具有很高的研究价值。已发现当使用此类材料时,抗肿瘤化学疗法和放射疗法可通过提高细胞杀伤作用的选择性并将全身不良反应降至最低来提高疗效。此外,催化纳米材料可以执行无能量的抗氧化循环,通过类似超氧化物歧化酶(SOD)和过氧化氢酶的活性清除最有害的活性氧。
从长远来看,这种独特方法预计会带来显著收益。然而,由于对这些新策略可能产生的潜在不良身体反应缺乏了解,必须谨慎行事。需要仔细分析这些纳米材料的生物相容性,特别是在生物动力学方面以及不可生物降解的无机纳米材料长期留存可能引发的问题。
