文摘
- •
A novel composite, PEI capped N-doped carbon dots (NCDs@PEI), was prepared via a facile microwave-assisted method.
- •
The as-prepared NCDs@PEI exhibited low toxicity and high catalytic effect to the anodic ECL of
nanosheets.- •
Reduced graphene oxide (rGO) was introduced to accelerate electron transfer rate and amplify the ECL signal.
- •
The fabricated ECL sensor exhibited multifunctional application in detecting DA, BPA, CT and HQ.
