From: Nanodetection of Head and Neck Cancer on Titanium Oxide Sensing Surface
SCC-Ag detection with a antibody and b GNS antibody. Tested on IDE-TiO2 surfaces with the above steps until 1 M of ethanolamine blocking. A linear sweep voltage of 0 to 2 V at 0.01 V step voltage was followed for the measurements. After interacting 1 nM of SCC-Ag, the current levels were increased in both cases; at the same time, it shows a higher current change with GNS antibody
