Enzymes fold into unique three-dimensional structures, which underlie their remarkable catalytic properties. The requirement to adopt a stable, folded conformation is likely to contribute to their relatively large size (>10,000 Da). However, much shorter peptides can achieve well-defined conformations through...

A solution surface-erosion route was successfully employed to produce one-dimensional (1D) ZnO nanostructures. ZnO nanorod arrays and three-dimensional urchin-like assemblies could be selectively obtained with different manipulations. In this process, zinc foil was introduced to an organic solution system and...
