It is unknown how the identity provided by protein coronas on the surface of chiral nanoparticles determines their blood circulation, distribution, and clearance fates of the nanoparticles . Here, we attempt to investigate how the mirrored surface of gold nanoparticles with distinct chirality reshapes the coronal composition that mediates their subsequent clearance from blood and biodistribution. We found that chiral gold nanoparticles exhibited surface chirality-specific recognition for the coronal components, including the lipoproteins, complement components, and acute phase proteins, ultimately resulting in distinct cell uptake and tissue accumulation . We observed that these stereoselective behaviors were correlated to subgroups of the corona composition that could bind to low-density lipoprotein receptors. Therefore, this study reveals how chirality-specific protein compositions selectively recognize and interact with cell receptors for chirality-mediated tissue accumulation. This study will deepen our understanding of how chiral nanoparticles/nanomedicine/nanocarriers interact with biological systems to guide the efficient fabrication of target nanomedicines.
目前尚不清楚表面手性纳米粒子的蛋白冠所提供的身份如何决定纳米粒子的血液循环、分布和清除命运。在这里,我们试图研究具有不同手性的金纳米粒子的镜像表面如何重塑介导其从血液中清除和生物分布的冠状组成。我们发现,手性金纳米粒子对冠状成分(包括脂蛋白、补体成分和急性期蛋白)表现出表面手性特异性识别,最终导致细胞摄取和组织积累的明显差异。我们观察到这些立体选择性行为与能够与低密度脂蛋白受体结合的冠状组成的亚组相关。因此,本研究揭示了手性特异性蛋白组成如何选择性地识别和与细胞受体相互作用,以实现手性介导的组织积累。本研究将加深我们对手性纳米粒子/纳米医学/纳米载体与生物系统相互作用以指导靶向纳米药物的有效制备的理解。
