“…Thus, the multiplexed detection of mycotoxins, aflatoxin B 1 , fumonisin B 1 , and deoxynivalenol in beer samples was presented following a competitive immunoassay format with LODs of 0.8, 5.6, and 24 ng/mL for aflatoxin B 1 , fumonisin B 1 , and deoxynivalenol, respectively, and an overall assay duration of 12 min [137]. Through the analysis of beers of different types and origin, the sensor performance was compared with those provided by established instrumental laboratory methods [138]. In addition, the simultaneous, label-free immunochemical detection of four allergens, bovine milk protein, peanut protein, soy protein, and gliadin, in 6.5 min, with LODs of 0.04, 1.0, 0.80, and 0.10 µg/mL, respectively, has been reported.…”
