Biosensor Electrode Films

For our PreciseAU™ biosensor electrode films, we apply our latest breakthrough vacuum coating technology that allows us to achieve the same film surface resistivity levels while using a smaller amount of metals during the sputtering process. This provides our customers with significant cost savings and reduces their exposure to volatile precious metal prices. Sputtering and slitting are both done in a clean room environment minimizing the risk of contamination. Our engineers utilize more than 50 years of experience within thin films to develop in-house adhesives and propriety solutions for dielectric spacers in our in-house coating formulation lab for our partners.
