Abstract： As a typical contaminant affecting the safety of many types of food， the identification of aflatoxin atlow concentrations in complex matrices has always been a difficulty in detection technology.Multimodal sensing systems have demonstrated unique advantages in enhancing the screening efciency of toxins and the adaptability of detection scenarios by integrating multi-source recognitionmechanisms and signal linkage strategies.This paper mainly introduces the principles ofrepresentativecomposite technologies suchas electrochemical-optical，magneticimmuno-photothermal，andfuorescence-colorimetric，andanalyzes thedeploymentofthese technologies inmultiseion and their practical application effects，which provide an important technological support for the dynamic regulation of food safety.

Keywords： aflatoxin; multimodal sensing; food testing; signal fusion; on site screening
