大多数凝胶在交联密度方面表现出纳米级的空间变化。我们展示了微凝胶和水凝胶中染料标记的交联分布的第一张3D超分辨率显微镜图像。揭示了以前从未在微凝胶中成像的纳米级特征的形态。
The majority of gels exhibit nanoscale spatial variations in crosslink density. We present the first 3D super-resolution microscopy images of dye tagged cross-link distributions in microgels and hydrogels. The morphology of nanoscale features never imaged previously in microgels, are revealed.
