Comparison of the general properties of the conventional methods of antibiotics detection with those based on electrochemical aptasensors.
| Method | Specificity | Special Requirements | Detection Time | Cost |
|---|---|---|---|---|
| Microbiological | Low | Specialized bacteriological laboratory | Minimum 3 h | Modest |
| HPLC | High | Organic solvents | <1 h | High |
| GC | High | Sample should be transformed into gaseous phase | <1 h | High |
| MS | High | Sample should be transformed into ionized state | <1 h | High |
| MS–HPLC | High | Organic solvent, transformation of the sample into ionized state. | <1 h | High |
| MS–GC | High | Sample should be transformed into ionized state | <1 h | High |
| ELISA | High | Sandwich assay using expensive antibodies | <1 h | High |
| Electrochemical aptasensors | High | Antifouling surfaces for minimizing interferences with food matrix | <1 h | Low |
