文摘
- •
An ultrasensitive nonenzymatic electrochemical immunosensor for HIgG detection was developed.
- •
AuNRs were used to catalyze the deposition of silver.
- •
Detection signal was greatly amplified by self-assembly of AuNRs and the subsequent silver enhancement.
- •
This immunosensor exhibited a extremely low detection limit.
