Use of LYO-GOLD in printing inks

Inks composed of gold nanoparticles had a lot of attention in the last decade towards printed electronics due to the properties of these nanoparticles, such as high thermal conductivity, excellent resistance to oxidation and tuneable optical properties. A novel nano gold ink for the inkjet printing process was prepared using our production technology. The synthesised gold ink presents a cost‐effective solution for the fabrication of paper‐based sensor applications.
