文摘
- •
A multilayer composite film of Dawson-type vanadium-substituted POMs and Au@Ag core–shell NPs was fabricated by LbL technique.
- •
The proposed sensor exhibits low detection limit, high sensitivity, fast response time and excellent anti-interference property.
- •
The proposed sensor was applied to detect l-cysteine in real sample with satisfactory results.
