Herein, a rapid signal amplified aflatoxin B1 (AFB1) detection system based on self-replicating catalyzed hairpin assembly (SRCHA) has been constructed.
Herein, a label-free fluorescent signal amplified system based on catalyzed hairpin assembly (CHA) was reported. In this system, two hairpin probes, H1 and H2, were well-designed in which G-quadruplex sequences...
