A new system based on dendritic polyethylene-cationic poly(p-phenylene ethynylene) core-shell nanoparticles was developed for live-cell imaging. By using the combination of molecular-wire and "dendritic effects" strategies, this design provides the new system with higher photoluminescence quantum yields, lower cell viability and better cellular permeability compared with free cationic poly(p-phenylene ethynylene), allowing it to exhibit remarkable improvements in fluorescence imaging for live cells.
一种基于树枝状聚乙烯 - 阳离子聚对苯撑乙炔核壳纳米粒子的新系统被开发用于活细胞成像。通过结合分子线和“树枝状效应”策略，与游离的阳离子聚对苯撑乙炔相比，这种设计赋予新系统更高的光致发光量子产率、更低的细胞活力和更好的细胞渗透性，使其在活细胞荧光成像方面表现出显著改进。
