Gold inks

The most of screen-printed electrodes employed as transducers of genosensors are made of carbon or gold inks. Further sections detail the most used probe immobilization strategies in these types of electrodes. 

Gold ink n. A printing ink whose principal pigment consists of bronze powder. 

Imitation gold ink n. A simulated gold ink that uses aluminum powder to produce the metallic luster. 

Thick-film copper metallization is typically selected for the low cost of the conductor inks in comparison to gold inks. Other fhick-film conductor inks, such as silver and palladium silver, are also used when low material cost is... 

There is very little published information on the thermal decomposition process for liquid gold films. Deram et al. recently published their work on the thermal decomposition and thin-film formation of a commercial thermoplastic liquid gold ink [50]. The exact composition of the formulation studied was not determined, but it was believed to consist of a gold mercaptide containing aryl or ester functional groups in combination with resins and microcrystalline paraffin wax. 

Heat-release transfers offer an alternative process in which the gold ink is applied to a wax coated paper. The application of these decals to ware is an automated process where machinery melts the wax and transfers the decals to the ware to be decorated. Although this method is much faster, and requires no drying time, it requires significant investment in machinery and is suited to much higher-volume industrial applications, and most of the gold decal business remains as water-slide decals. 

The use of decals for bright gold decoration was hindered for a long time by the fact that dissolution of the gold layer and subsequent reactions occurred between the gold ink and the components...
