In article number 1803551, Zhiyang Li, Xuehao Wang, Yuanjin Zhao, and co‐workers present mussel‐inspired photonic crystal (PhC) barcodes with graphene oxide (GO) encapsulation for multiplex miRNA detection. The GO‐based hybridization chain reaction strategy realizes low abundance and high sensitivity miRNA quantification. At the same time, multiplex detection is achieved by employing different GO‐decorated PhC barcodes with high accuracy and reproducibility.
