A cleaner alternative to existing raw materials
The mining of precious metals for use in sensor technologies often have a significant environmental impact. Mining of gold, a material used in Point-of-Care diagnostic testing, accounts for over 100 million metric tonnes of CO2-e annually, equivalent to more than double the emissions produced in Portugal in 2021. It also leads to the loss of land and long-term impacts on biodiversity and local communities.
In biosensor applications, replacing gold electrodes with Gii delivers a direct saving of 0.5KG* CO2e per sensor. Therefore, for the approximately 100,000 sensors manufactured this year using Gii, there has been a saving of 50,000 kg CO2e. This is equivalent to driving around the world in a car four times.
