Sumario:Color‐Switchable Microlasers In article number 2202326 by Haiou Zhu, Cun‐Zheng Ning, Shuangchen Ruan, and co‐workers, a permeable color‐switchable whispering‐gallery‐mode (WGM) microlaser for ultrasensitive detection of biomarker is developed. The more sensitive concentration dependence allows even visual distinguishability of small changes in biomarker concentration. Due to the narrow cavity modes and largely shifted spectral peaks, the microlaser output from the microsphere can act as “normal‐abnormal” logic signal to integrate into multiplexing detection assays.
