Uranium has been defined in material research engineering field as one of the most energetic radioactive elements in the entire Mendeleev periodic table. The manipulation of uranium needs higher theories and sophisticated apparatus even in nuclear energy extraction or in many other chemical applications. Above the nuclear exploitation level, the chemical conventional approaches used, require a higher temperature and pressure to control the destination of ionic form. However, it has been discovered later that at biological scale, the manipulation of this actinide is possible under friendly conditions. The review summarizes the relevant properties of uranium element and a brief characterization of nanoparticles, based on some structural techniques. These techniques reveal the common link between chemical approaches and biological assistance in nanoparticles. Also, those biological entities have been able to get it after reduction. Uranium is known for its ability to destroy ductile materials. So, if biological cell can really reduce uranium, then how does it work?
在材料研究工程领域，铀被定义为整个门捷列夫元素周期表中能量最高的放射性元素之一。即使在核能提取或许多其他化学应用中，对铀的操作也需要更高深的理论和精密的仪器。在核开发层面之上，所采用的化学常规方法需要更高的温度和压力来控制离子形式的去向。然而，后来人们发现，在生物尺度下，在友好的条件下对这种锕系元素进行操作是可行的。本综述基于一些结构技术，总结了铀元素的相关特性以及纳米颗粒的简要特征。这些技术揭示了纳米颗粒化学方法与生物辅助之间的共同联系。此外，那些生物实体在还原后能够获得铀。铀以其破坏韧性材料的能力而闻名。那么，如果生物细胞真的能还原铀，它是如何做到的呢？
