Sensitive Immunosensor Developed for Accurate Quantification of Alpha-Fetoprotein via Evanescent Field-Enhanced Fluorescence Imaging
Single-Molecule Sandwich Immunoassay for Quantification of Alpha-Fetoprotein Alpha-fetoprotein (AFP) is a protein that is mainly produced during pregnancy in the developing fetus. However, in some cases, elevated levels of AFP in adults can indicate a potential risk for developing liver cancer. In order to accurately and effectively detect the levels of AFP in adult blood samples, researchers have developed a highly sensitive immunosensor based on a gold nanopatterned chip. This biosensor works by creating a sandwich of antigen between the AFP antibody on the chip, which has been modified with protein A/G, and the secondary antibody, which is a monoclonal anti-human-AFP labeled with biotin (biotin-labeled anti-AFP). The AFP concentration is then determined based on evanescent field fluorescence signal, which is generated by the interaction between biotin-labeled anti-AFP and a streptavidin-labeled fluorescence dye. The gold nanopatterned chip is specially modified with dithiobis(succinimidyl propionate) and protein A/G, which allows for the immobilization of the AFP antibody. This technology enhances the sensitivity of the immunoassay, as it allows for the AFP concentration to be measured in a wide dynamic linear range of 720 zM–10 nM, with a detection limit of 720 zM. This technology has significant benefits over conventional chemiluminescence immunosensors, as it achieves a much higher sensitivity of about 40,000-fold. This makes it a valuable tool for clinical assays of AFP. The immunoassay can detect a wide range of AFP concentrations with high accuracy and sensitivity. One of the key features of this technology is the use of biotin-based immunoassays. Biotin is a water-soluble vitamin that plays a vital role in various metabolic functions in the human body. Because of its high binding affinity to streptavidin, biotin can be used as a label for a variety of immunoassays. This technology utilizes biotin-labeled anti-AFP antibody on the chip, which enhances the sensitivity of the immunoassay. In conclusion, the single-molecule sandwich immunoassay based on a gold nanopatterned chip is a major breakthrough in the accurate and effective detection of AFP in clinical assays. The use of biotin-based immunoassays enhances the sensitivity of the immunoassay, which makes it a valuable tool for early detection of liver cancer in patients with elevated levels of AFP. The potential applications of this technology could be limitless, and it could pave the way for future developments in immunosensing.
