- •
The preparation of biosensor based on DA aptamer labeled CDs and nano-graphite is simple, rapid and convenient.
- •
The biosensor has high sensitivity with a linear range of 0.10–5.00 nM and detection limit of 0.055 nM.
- •
The as-prepared biosensor also has good selectivity for specific recognition of dopamine.
- •
Sample preparation is very simple just with dilution.
- •
All the materials used in the study are low toxic or even nontoxic which avoids environmental pollution.
