Hard and soft : Binding of inorganic Pt@Fe 3 O 4 Janus particles to WS 2 nanotubes through their Pt or Fe 3 O 4 domains is governed by the difference in Pearson hardness: the soft Pt block has a higher sulfur affinity than the harder magnetite face; thus the binding proceeds preferentially through the Pt face. This binding preference can be reversed by masking the Pt face with an organic protecting group.
