Circularly ordered self-assembly (micro-ring) of manganese dioxide nanocrystals were formed simply by dewetting a manganese dioxide colloidal aqueous solution on mica. The balance between the repulsive force of the nanocrystals and the compressive force of shrinking droplets plays an important role in forming this peculiar nanosize assembly.
