Abstract

A photoactive hybrid nanostructure for near-infrared quantitative cell imaging is reported by Hua Kuang and co-workers in article number 1703408. AuNanorod-PtAgS nanostructures are obtained with high yield. Application of the composite in fluorescent live cell imaging reveals a limit of detection for microRNAs of 0.0082 attomol per ng RNA. This system could provide further inside into the fate of microRNA in live cells.
