Dual-aptamer-activated RCA-MOF synergistic platform for visual detection of leukemia-derived exosomes.
The sensitive, point-of-care detection of acute myeloid leukemia (AML)-derived exosomes is essential for non-invasive diagnosis and therapy monitoring, but remains technically challenging. Here we report a colorimetric biosensor based on a dual -aptamer-initiated catalytic cascade, where simultaneous recognition of exo...
