Asymmetric Mach–Zehnder Interferometer Based Biosensors for Aflatoxin M1 Detection

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...
