DISCERN: Dual-Aptamer-Initiated Sensing Circuit via Engineered Nanozyme for Leukemia Stem Cells Phenotyping
Abstract
Leukemia stem cell (LSC) phenotyping offers significant potential to enhance minimal residual disease (MRD) monitoring in acute myeloid leukemia (AML), improving therapeutic evaluation and relapse prediction. However, current approaches lack the sufficient sensitivity and specificity to reliably detect rare chemotherapy-resistant LSCs (crLSCs) or identify stem-like phenotypic states, limiting clinical translation. Here, we develop DISCERN (Dual-Aptamer-Initiated Sensing Circuit via Engineered Nanozyme), a colorimetric platform for ultrasensitive LSC phenotyping. DISCERN employs a dual-aptamer system targeting colocalized surface markers (CD33 and CD123) for high-specificity recognition. Its exceptional sensitivity (limit of detection
