A Test Strip Builds More Places for a Virus Signal to Land
An enzyme-free molecular bridge amplifies Chikungunya RNA detection on a portable lateral-flow format.
Summary
An enzyme-free molecular bridge amplifies Chikungunya RNA detection on a portable lateral-flow format.
Chinese researchers built a two-round catalytic hairpin system that creates multiple binding sites before gold-platinum nanoparticles deepen the visible line. Chikungunya served as the model target. The approach is designed to avoid thermal cycling and fluorescence readers, but field performance across mosquito-borne viruses still requires validation.
