CHAI-sEV: A Programmable Hairpin-Driven Cas9 Platform with AI Integration for Dual-Protein Profiling and Intelligent Classification of Tumor-Derived Small Extracellular Vesicles
Multiplexed protein profiling of tumor-derived small extracellular vesicles (TsEVs) requires signal-conversion strategies that are sensitive, low-background, and orthogonal. Collateral-cleavage CRISPR assays based on Cas12a or Cas13a provide efficient amplification but can compromise single-pot multitarget detection,...
