文摘
- •
Ultrasensitive sandwich-type immunosensor was developed for the detection of TSGF.
- •
rGO-TEPA added loading capacity of Ab1 and facilitated electron transferability.
- •
Ag-CeO2 nanocomposite facilitated the catalytic reduction of H2O2.
- •
The immunosensor exhibited an extremely low detection limit of 0.2 pg/mL for TSGF.
