Target-to-signal conversion and spatial enrichment cascade boost CRISPR/Cas12a biosensing for trace-level pathogen detection.
PubMed · 2026-05-28
Scientists developed a two-stage molecular detection system that dramatically amplifies weak signals from pathogens, making CRISPR-based diagnostic tools sensitive enough to detect disease-causing organisms at trace levels.
1
A dual-stage cascade system (target-to-signal conversion + spatial enrichment) was engineered to amplify CRISPR/Cas12a detection sensitivity to trace levels.
2
The approach enables detection of pathogens at concentrations far below what standard CRISPR biosensors can achieve, though specific numerical limits of detection were not provided in the abstract.
3
Spatial enrichment of signals—concentrating them in one location—was identified as a key innovation boosting overall biosensor performance.
