Electrochemical Immunoassay of Human Chorionic Gonadotrophin Based on Its Immobilization in Gold Nanoparticles‐Chitosan Membrane

“…During the past decades, immunoassays using the specific antigen -antibody immunoconjugates for analytical purposes have been extensively developed in many fields including food industry [1,2], environmental protection [3,4] and clinical control [5 -7]. In order to avoid the utilization of radioisotopic labels with their apparently associated related problems such as disposal and operation safety, many electrochemical immunoassay systems combine the features of fast, sensitive, inexpensive and miniaturizable electrochemical measurement systems with the exquisite specific immunoassay procedures have been widely used for determination of clinically important substances [8 -10].…”

High-sensitive flow-based kinetic exclusion assay for okadaic acid assessment in shellfish samples

“…In such kind of cases, immunoassay approaches based on competitive formats are highly preferred (Bilitewski, 2000). These competitive formats can be performed directly or indirectly.…”

Recognition behavior of chiral nanocomposites toward biomolecules and its application in electrochemical immunoassay

“…Immunoassay is a significant subject in clinical diagnosis, food industry, environmental analysis, and chiral recognition [16][17][18][19]. Moreover, based on the high sensitivity, low cost and compatibility with micro-fabrication technology of transducers, electrochemical methods are well suited for the rapid monitoring of chiral discrimination [20].…”
