Inspired by Pearson's hard and soft acid-base (HSAB) principle, uniform amorphous Ni(OH)2 nanoboxes with intact shell structures and various sizes are fabricated by L. Guo and co-workers on page 3147. The selection of S2O32 as the coordinating etchant toward the Cu2O templates as well the optimization the reaction conditions, such as the solvent system and the use of a surfactant, are crucial for the formation of well-defined and high-quality Ni(OH)2 nanoboxes. Ni(OH)2 nanoboxes demonstrate an improved electrochemical sensing ability for glucose. The advantages of high sensitivity, low detection limit, wide detection range and long-term storage stability of the biosensor, which might due to their amorphous and hollow-structure features, make these nanoboxes promising in analytical applications.
