Our news editors obtained a quote from the research, "Carbon nanotubes (CNTs)/gold nanoparticles' (NPs) hybrids were used as amplified platform for assembling large numbers of DNA on the electrode, which also improve the bioactivity and stability of the electrode. After the QD-DNA signal probe was recognized with target DNA (t-DNA), the amplified ECL signal for the detection of target DNA was obtained. Furthermore, magnetic nanoparticles were employed for cell aptamers immobilization, the same QD nanocluster-DNA probe was also extended for electrochemical detection of cancer cells using sensitive anodic stripping voltammetry (ASV) method, which simplified the separation procedures and improved the sensitivity."
According to the news editors, the research concluded: "It is anticipated that the assays could provide promising and cost effective approach for the early and accurate detection of DNA and cancer cells."
