Abstract

In this study, we described a novel and effective flower-like ZnO nanostructure assisted Reverse Transcription Loop-Mediated Isothermal Amplification (RT-LAMP) method to detect Japanese Encephalitis Virus (JEV). The effects of different concentrations of ZnO nanoflower on the RT-LAMP reaction were investigated. With the increase of concentration of ZnO nanoflower, RT-LAMP reaction obtained optimization, until the concentration exceeded 1.5nM, RT-LAMP reaction was inhibited. Made 1nM as optimum concentration of ZnO nanoflower, we found that optimum RT-LAMP reaction temperature and time were 60°C and 30min, respectively. The optimization might be connected with good adsorption to DNA and thermal conductivity of ZnO nanoflower, but mechanism of the RT-LAMP reaction affected by ZnO nanoflower needs to be explored further.
