Target-Induced Electrochemical Sensor Based on Foldable Aptamer and MoS₂@MWCNTs–PEI for Enhanced Detection of AFB1 in Peanuts

Advances in Aptamer-Based Conjugate Recognition Techniques for the Detection of Small Molecules in Food

“…When compared to other developed aptasensors, its accuracy and sensitivity were much better than those of a luminescence resonance energy transfer aptasensor (LERT) [117], but these were equal to those of the other reported EASs [118], with a linear range of 0.1~10,000 pg/mL and a LOD of 0.012 pg/mL. There has been some research undertaken on using single Fc (Figure 8D) [119] and other redox reporters to detect small molecules in food, such as MBs (Figure 8E) [120], [Fe (CN)6] 3−/4− (Figure 8F) [121], MB−Fc (Figure 8G) [122], and THI−Fc (Figure 8H) [123].…”
