文摘
- •
Platinum nanoparticles as basis for a novel environmental monitoring biosensor.
- •
Nanoparticles are modified with DNAzymes, enhancing the conductivity of the sensor.
- •
Nanoparticle conductivity is highly sensitive to changes in their environment.
- •
The proposed biosensor is able to detect lead concentrations as low as 10 nM.
- •
The biosensor is simple, selective, cost effective, reusable and fast.
