Nanostructures: Amorphous Ni(OH)₂ Nanoboxes: Fast Fabrication and Enhanced Sensing for Glucose (Small 18/2013)

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.
