Abstract

Upon entering into the biological environments, the surface of the nanoparticles is immediately coated with proteins and form the so-called a protein corona due to which a nanoparticle changes its "synthetic" identity to a new "biological" identity. Different types of nanoparticles have different protein binding profiles, which is why they have different protein corona composition and therefore it cannot be said that there is a universal protein corona. The composition and amount of protein in the corona depends on the physical and chemical characteristics of the nanoparticles, the type of biological medium and the exposure time. Protein corona increases the diameter but also changes the composition of the surface of the nanoparticles and these changes affect biodistribution, efficacy, and toxicity of the nanoparticles.

摘要

进入生物环境后,纳米颗粒的表面会立即被蛋白质包裹,形成所谓的蛋白质冠层,由于这一过程,纳米颗粒将其“合成”身份转变为新的“生物”身份。不同类型的纳米颗粒具有不同的蛋白质结合模式,这就是它们具有不同蛋白质冠层组成的原因,因此不能说存在通用的蛋白质冠层。冠层中蛋白质的组成和数量取决于纳米颗粒的物理和化学特性、生物介质的类型以及暴露时间。蛋白质冠层不仅会增加纳米颗粒的直径,还会改变其表面组成,而这些变化会影响纳米颗粒的生物分布、功效和毒性。
