MicroRNA detection using lateral flow nucleic acid strips with gold nanoparticles

► In this study, a fast and sensitive method is developed to detect microRNA. ► One fmol of the tested microRNA were detected without the silver enhancement. ► Five amol of the tested microRNA were detected with the silver enhancement. ► This method does not need equipments. ► It is simple, convenient, fast, and suitable for point-of-care.
