Scientists have created a new type of chemosensor (demonstrated for lactic acid sensing) which functions with electricity but without the need for reference electrodes or battery power.
Scientists introduce a breakthrough carbon-based sensor for detecting lactic acid levels in saliva -- avoiding the need for an electrical power sourceScientists have created a new type of chemosensor which functions with electricity but without the need for reference electrodes or battery power.
Underpinned by a Gii-Sens electrode platform, the Gii chemosensor could have potential for highly sensitive lactic acid testing in remote locations without needing a lab. The sensor was proven to detect lactic acid, a byproduct generated by the body when it metabolises carbohydrates or glucose for fuel, for example, during exercise. High levels of lactic acid are linked with higher risks of falling unconscious or into a coma and major organ failure.
Referenced as 'Graphene Foam' in the paper, Gii-Sens, the technology underpinning the chemosensor, is an electrode produced by Integrated Graphene. Gii-Sens incorporates Gii™, a pure, porous, 3D carbon nanostructure that delivers low cost and avoids the use of unsustainable noble metals like gold. "This sensor, using Gii-Sens technology, addresses some of the main limitations with non-wireless current lactic acid enzyme tests," said Professor Marken,"It will allow for a more simply operated sensor -- opening up the potential for more regular, less invasive and more reliable tracking of lactic acid, even during athlete performance."
Jean-Christophe Granier, Chief Executive Officer of Integrated Graphene, commented:"This development is another clear use case of Gii-Sens being integrated into sensing products and offering versatile applicability.
