了解纳米结构的生物纳米尺度识别对纳米材料的设计和应用至关重要,但相关信息还没有得到很好的理解。在这项研究中,发现生物纳米尺度识别是细胞命运和治疗的基础。例如,1 T相(八面体配位)单层MoS 2对纤连蛋白的亲和力明显强于2 H结构(三角棱镜配位),并促进细胞伸展和分化。货车范德华能和增加的转向分量有助于纤连蛋白在1 T-MoS 2结构上的高粘附。由于强疏水相互作用,1 T-MoS 2对脂质体的亲和力(KD,6.59 × 10−7 m)显著强于2 H-MoS 2(1.21 × 10−6 m)。八面体协调的原子结构,提高细胞活力,通过提高神经突长度的存在首先证明了随机森林和结构方程模型。因此,八面体配位使α-突触核蛋白解聚(例如,通过减少β折叠和增加卷曲结构),并保护细胞和宿主免受帕金森病的影响。作为原理证明,这些发现表明生物纳米尺度识别是生物材料和细胞疗法设计的基础。
Understanding the bionanoscale recognition of nanostructured architectures is critical to the design and application of nanomaterials, but the related information is not well understood. In this study, it is found that bionanoscale recognition underlies cell fate and therapy. For example, 1T phase (octahedral coordination) monolayer MoS2 exhibits a markedly stronger affinity for fibronectin than the 2H structure (triangular prism coordination) and promotes cell spreading and differentiation. The van der Waals energy and increased turn components contribute to the high adhesion of fibronectin onto the 1T‐MoS2 structure. 1T‐MoS2 exhibits a significantly stronger affinity (KD, 6.59 × 10−7 m) for liposomes than 2H‐MoS2 (1.21 × 10−6 m) due to strong hydrophobic interactions. The existence of octahedrally coordinated atomic structures that improve cell viability by enhancing the neurite length is first proven by random forest and structural equation models. Consequently, octahedral coordination disaggregates α‐synuclein (e.g., by decreasing β‐sheets and increasing coil structures) and protects cells and hosts against Parkinson's disease. As a proof‐of‐principle demonstration, these findings indicate that bionanoscale recognition underlies the design of biomaterials and cell therapeutics.
