Paper Title :
Sensing of Lung Cancer using Surface Potential

Author :Sungsoo Na

Article Citation :Sungsoo Na , (2017 ) " Sensing of Lung Cancer using Surface Potential " , International Journal of Mechanical and Production Engineering (IJMPE) , pp. 46-47, Volume-5,Issue-8

Abstract : A label-free and high-sensitive sensing method of lung cancer mutations using surface potential and a gold nanoparticle (AuNP) is developed. The detection is based on the evaluation of the surface potential of each AuNP. When AuNPs are modified with probe DNA (AuNP–pDNA), the surface potential is shifted towards the negative potential due to the negatively charged DNA backbone. When AuNP–pDNA captures target mutant DNA through DNA hybridization, an additional surface potential shift occurs. The platform is able to sense lung cancer mutant DNA with a limit of detection (LOD) of 3.3 pM. Keywords- Lung Cancer; Surface Potential; Gold Nanoparticle; Probe DNA
