dc.description.abstract | Assessment of Kirsten rat sarcoma viral oncogene homolog (KRAS) and epidermal growth factor receptor (EGFR) mutations are essential for targeted therapies of patients with non small cell lung cancer. In this report, we propose a label-free and high-sensitive detection method of KRAS and EGFR mutations using KPFM and a gold nanoparticle (AuNP) based platform that densely adsorbs probe DNA and minimizes the sensing area. 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 further captures target mutant DNA through DNA hybridization, an additional surface potential shift occurs. The platform is able to detect KRAS mutant DNA (13 mer) and EGFR mutant DNA (84 mer) with a limit of detection (LOD) of 3.3 pM. Furthermore, the platform is able to detect selectively the KRAS mutant DNA from its wild-type DNA. Our proposed label-free and high-sensitive KPFM method has shown potential glimpses of a personalized medical diagnosis for cancer patients. (C) 2016 Elsevier B.V. All rights reserved. | - |
