Asymmetric Mach–Zehnder Interferometer Based Biosensors for Aflatoxin M1 Detection
In this work, we present a study of Aflatoxin M1 detection by photonic biosensors based on Si₃N₄ Asymmetric Mach-Zehnder Interferometer (aMZI) functionalized with antibodies fragments (Fab'). We measured a best volumetric sensitivity of 10⁴ rad/RIU, leading to a Limit of Detection below 5 × 10(-7) RIU. On sensors functionalized with Fab', we performed specific and non-specific sensing measureme...
متن کاملDesign and Optimization of SiON Ring Resonator-Based Biosensors for Aflatoxin M1 Detection
In this article, we designed and studied silicon oxynitride (SiON) microring-based photonic structures for biosensing applications. We designed waveguides, directional couplers, and racetrack resonators in order to measure refractive index changes smaller than 10-6 refractive index units (RIU). We tested various samples with different SiON refractive indexes as well as the waveguide dimensions ...
متن کاملBiosensors based on cholinesterase inhibition for insecticides, nerve agents and aflatoxin B1 detection (review)
The present review reports the research carried out during last 9 years on biosensors based on cholinesterase inhibition for nerve agents, organophosphorus and carbammic insecticides, and aflatoxin B1 detection. Relative applications in environmental and food areas are also reported. Special attention is paid to the optimization of parameters such as enzyme immobilization, substrate concentrati...
متن کاملAflatoxin M1 in Milk - FSA4018
Aflatoxins are mycotoxins of major concern to the dairy industry. Most mycotoxins are found in grain, usually grown in a drought, although they may contaminate pasture grass and occasionally hay. Most frequently, aflatoxins are found in corn (see Figures 1-3) and cottonseed, and sometimes in their byproducts, but also on rare occasions in soybeans or distiller’s grain. Peanut products also may ...
متن کاملAdvancement in electrochemical DNA-biosensors for GMOs detection: A review
Genetically modified organisms (GMOs) are plants or animals whose genetic make-up has been transformed by recombinant DNA technology, which has new features such as resistance to herbicides, virus and insect. Recently, genetic modification of food products has increased in order to reduce world poverty and hunger and increase food production However, the impact of GMOs on the human health is a ...
