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,...

This one-pot Cas13a/Cas12a cascade fluorescence biosensor enabled quantitative detection of miRNA-21 over a concentration range of 1-1000 pmol/L within 60 min, with a low detection limit of 0.66 pM.

This review discusses how nanomaterials facilitate signal generation and transduction, how microfluidics automates, multiplexes, and miniaturizes "all-in-one" devices, and how orthogonal CRISPR systems can enable robust multiplexing.
