长距离三维纳米图案的产生是材料化学的主要目标。在这里，我们报告了一个战略，创造这样的系统使用病毒晶体作为支架，可以渗透金属，特别是钯和铂。无机组分有效地填充在多孔大分子晶体结构内，为在纳米长度尺度上图案化这些材料提供了途径。为了验证金属渗透的质量，使用SEM-EDX来确定金属在晶体上的均匀分布，并且使用TEM来确认金属被限制在晶体的多孔结构内。
The generation of long-range three-dimensional nanoscopic patterns is a major goal in materials chemistry. Here we report a strategy for creating such systems using virus crystals as scaffolds which can be infiltrated with metal specifically palladium and platinum. The inorganic component effectively packs within the porous macromolecular crystal architecture, providing a route for patterning these materials on the nanometer length scale. To verify the quality of the metal infiltration, SEM-EDX was used to determine the homogeneous distribution of metal across the crystal, and TEM was used to confirm that the metal was confined within the porous structure of the crystal.
