Researchers Expand the Tool Kit of Colloid Particles Making New Coloured Finishes Possible

Scientists at the Max Planck Institute of Colloids and Interfaces have used ion bombardment and gold metallisation to produce a new family of particles whose bonding behaviour can be chemically tailored. With these particles, scientists hope not only to be able to perform better research on the dynamics of solids and molecules. The discovery could also bring about, among other things, the development of new finishes which change their colour with temperature.
