Detection of single nanoparticle (NP) collision is being researched by electrocatalytic amplification method. One system for this consists of Pt NP, Au ultramicroelectrode(UME), and hydrazine oxidation reaction. When Pt NPs are collided on Au UME, increasing current response is observed via hydrazine oxidation. In order to make biosensor-device from this concept, it is important that the flexibility of metal substrate is obtained. So, alternative metal was found. It is the metal palladium (Pd) which is employed for the electrode. The substituted Pd UME has wide potential range available which can be applied for detection of NP adsorption. In case of detection of Pt single nanoparticle collision using Au UME, the electrode is applied by near 0 V (vs. Ag/AgCl). On the other hand, available potential of Pd UME is applied by 0.1 ~ -0.2 V for that; the signal is observed without changing shape.
