Electrochemical detection of celiac disease-related anti-tissue transglutaminase antibodies using thiol based surface chemistry

Towards a blocking-free electrochemical immunosensing strategy for anti-transglutaminase antibodies using screen-printed electrodes

“…In other cases, where shorter analysis times are achieved, the procedure is more complicated with several steps [42][43][44]. Only a blocking-free strategy was published by Pividori et al [45] using graphite-epoxy composite electrodes, but a complex methodology with several time-consuming (20 min) washing steps to prevent nonspecific adsorption is carried out.…”

Recent advances in biosensors for diagnosis of celiac disease: A review

“…Dulay, Lozano‐Sánchez, Iwuoha, Katakis, and O’Sullivan () continued the work of Rosales‐Rivera et al () for the development of an ECIS for the detection of TGA. The instrumentation and electrochemical setup were similar to as adapted for AGA detection (Rosales‐Rivera et al, ).…”

Direct immobilization of antibodies on a new polymer film for fabricating an electrochemical impedance immunosensor

“…Among chemical cross-linking method, various support matrixes with functional groups such as carboxylic acid and amine have been used to immobilize antibodies [6,7]. Traditionally, those support matrixes for immobilization antibodies procedures usually involve three separate steps.…”
