Cover Story: We developed for the first time a functional immobilized CRISPR/Cas13a assay in a chitosan hydrogel-coated 3D-printed 96-well plate, enabling unamplified quantification of three distinct miRNAs simultaneously associated with Alzheimer’s disease, achieving femtomolar sensitivity with an LOD of 0.1 fM. This immobilization strategy enables multiplex detection, providing a simplified, efficient mix and read platform, removing complex sample preparation steps and eliminating specialized training requirements. Target binding to CRISPR RNA triggers Cas13a collateral RNase activity, cleaving a fluorescent reporter with real-time reaction monitoring. This cost-effective method (USD 3.5/plate) is validated in patient plasma samples exhibiting low cross-reactivity (<5%). It has great potential in detecting multiple pathogens and clinical disorders. View this paper
