Due to its compatibility with solvents, laser ablation in liquids allows the embedding of nanoparticles into polymers that are suitable for injection molding or extrusion, for example to realize antibacterial applications.
At Hannover Messe (running from April 23rd to 27th, 2012),Particular will present and give away polymeric “silver coins” and “gold coins” that consist of TPU (a transparent polymer without color) with pure metallic nanoparticles.

In these samples (that can be used as coins for supermarket carts), small amounts of nano-gold or nano-silver lead to a red or yellow color - without any use of dyes. They demonstrate how laser-generated nanoparticles can be used in thermoplastic processes like injection die casting without losing their homogeneous distribution in the polymer.
