- Additional information
- A novel electrode material is described that can simultaneously determine multiple analytes, which is difficult to achieve with current electrode materials because of their narrow specificity. Limits of detection were <10nM with selectivity maintained in the presence of several possible interfering species. Human serum samples validated the applicability to blood analysis. This discovery opens the possibility of many new electrochemical biosensors and potential applications, for example, in early disease diagnosis and water sampling.
