Bioreceptor-free, sensitive and time–resolved electrochemical detection of patulin fungal toxin using a reduced graphene oxide@SnO2 nanocomposite |
| 초록 |
In this research, we synthesized a reduced graphene oxide/tin oxide (rGO/SnO2) composite for the electrochemical detection of fungal contaminant, patulin (PAT). The resulting rGO/SnO2 composite exhibited promising electrochemical properties with outstanding performance to detect PAT levels in contaminated apple juice samples. The differential pulse voltammetric response of the rGO/SnO2 composite electrode exhibited a linear relationship with PAT concentration in the 50–600 nM range and had a lower detection limit of 0.17nM. The sensor electrode exhibited high sensitivity, reliable reproducibility, and good selectivity. We found that the electrochemical sensor had ability to rapidly detect PAT in apple juice samples without the need of extraction or clean-up steps and achieved a higher recovery rate (74.33±0.70 to 99.26±0.70%) within a short-time analysis than did by the HPLC (61.97±1.78 to 84.31±1.96%), thus illustrating its feasibility for agricultural and food safety industries. |
