Abstract
Metal nanoparticles embedded in the carbon film electrodes were fabricated by co-sputtering of two metals and carbon and applied for detecting heavy metals such as selenium and arsenic, and also detecting sugar markers for the diagnosis of severe intestinal diseases. For improving the sensitivity for detecting heavy metal ions, the Au was plated on the surface of Au nanoparticles embedded electrodes and uniform nanoparticles with larger surface area can be fabricated and achieved to detect As3+ and Se4+ with low detection limit around 10 ppb. For detecting sugar markers, we fabricated Ni and Cu nanoalloy embedded in the carbon film and achieved the detection limits about 2 order of magnitude lower than that of commercially available gold electrode.
