Interests: nano-enabled biosensing, nanoparticles; nanowires, elecrochemical sensing approaches; infectious diseases; global health; food/water safety; biodefense; product integrity
This Special Issue will cover biosensing technologies based on nanoparticles of all forms, for a variety of detection and diagnostic applications: infectious and chronic diseases, biomarker monitoring and discovery, pathogen contamination in food and the environment, drug compliance monitoring, plant and animal disease monitoring, epidemiological assessment, product integrity and authentication, bio-energy quality monitoring, and many other applications. Biological receptors may include antibodies, DNA probes, aptamers, enzymes, molecularly imprinted polymers, glycoproteins, and many other forms of target recognition. Detection modalities may include optical, electrical, electrochemical, acoustic waves, magnetic, and other forms and combinations of signal generation. Microfluidics, lab-on-chip, and integrated platforms are most welcome.

Title: Magnetic Bead-Based Immunoassay for Aflatoxin B1 via Inner Filter Effect of Gold Nanoparticles.

Abstract: A simple, rapid and sensitive fluorescence immunoassay for the detection of aflatoxin B1 (AFB) has been developed, which is based on the fluorescence quenching of fluorescein caused by gold nanoparticles via inner filter effect. As immunosensing probe magnetic beads were coated with aflatoxin B1-bovine serum albumin conjugates, anti-AFB antibodies coated gold nanoparticles could bind with the magnetic beads through the antibody–antigen reaction; while such binding was competitively inhibited by the addition of AFB. After magnetic separation, the supernatant, which contained the unbound gold nanoparticles, was utilized to quench the fluorescence of fluorescein. The fluorescence intensity at 510 nm was inversely proportional to the AFB concentration. This method could be easily extended to detect other mycotoxins and organic pollutants.
