Spherical nucleic acid reporter-based cascade CRISPR/Cas12a amplifier for stable and sensitive biosensing of circulating tumor DNA†
Abstract
Stable and sensitive ctDNA biosensing in complex biological fluid is highly important but still remains a challenge. Herein, we develop a spherical nucleic acid reporter-based cascade CRISPR/Cas12a amplifier with improved stability and sensitivity (5 orders of magnitude).
