Plug n' play protein crystals

Almost a hundred years ago in 1929 Linus Pauling presented the famous Pauling's Rules to describe the principles governing the structure of complex ionic crystals. These rules essentially describe how the arrangement of atoms in a crystal is critically dependent on the size of the atoms, their charge and type of bonding. According to scientists from the Biohybrid Materials Group of Aalto University Finland led by Mauri Kostiainen similar rules can be applied to prepare ionic colloidal crystals c...
