文摘
- •
A multiple signal amplification ECL immunosensor of eco-friendly CdSe QDs for brombuterol determination was developed.
- •
Besides substrates, AuNPs and PAMAM-SNR were creatively used to accelerate the electron transport between electrode and QDs.
- •
SNR-PAMAM with numerous amino groups also could be employed to bond abundant actived QDs to amplify ECL signal.
- •
Competitive immunoassay was performed with ECL to detect small molecules of brombuterol.
- •
It provided a method for detecting Brom and enlarged the usage of QDs, AuNPs and SNR-PAMAM in ECL biosensing.
