Near-infrared (NIR) aggregation-induced emission luminogens (AIEgens) are excellent probes for tumor imaging, but there still is space to improve their imaging specificity and sensitivity. In this work, a strategy of tandem targeting and dual aggregation of an AIEgen is proposed to achieve these two purposes. An AIEgen, β-tBu-Ala-Cys(StBu)-Lys(Biotin)-Pra(QMT)-CBT (
