TEM images of cells labelled with GNR-PEG

TEM images of cells labelled with GNRs capped with PEG-COOH. GNRs are tightly packed in subcellular vesicles, which is ultimately translated in plasmon coupling. Therefore, cells labelled with these GNRs did not have the typical GNRs optical properties.本数据集涵盖经羧基聚乙二醇（PEG-COOH）包覆的金纳米棒（Gold Nanorods, GNRs）标记的细胞的透射电子显微镜（Transmission Electron Microscopy, TEM）图像。此类金纳米棒紧密聚集于亚细胞囊泡内，最终引发等离激元耦合效应。因此，经上述金纳米棒标记的细胞并未展现出金纳米棒的典型光学特性。
