Abstract

Sarcosine as a prostate cancer biomarker has been detected by using Si naowire based electrolyte/NiOx/SiO2/n-Si sensor for the first time. A long nanowire (14 m) by chemically etched is observed by scanning electron microscope (SEM) images. A 2 nm-thick NiOx membrane on SiO2/n-Si structure shows low concentration of 1 pM H2O2 sensing as well as sarcosine of 10 pM has been detected because Ni2+ oxidation state changes to Ni3+ state.
