Method and system for detection of aflatoxin

A method for detecting aflatoxin, the method comprising:

• conducting a test solution through a flow path formed in an aflatoxin-detection device, the flow path comprising a plurality of nanocomposite strips formed therein;
• exposing the aflatoxin-detection device to ultraviolet illumination, the ultraviolet illumination inducing fluorescence of certain nanocomposite strips of the plurality of nanocomposite strips;
• and
• responsive to a fluorescence intensity of the certain nanocomposite strips, determining a concentration of aflatoxin in the test solution.

A method for producing an aflatoxin-detection device, the method comprising:

• forming a stencil having a plurality of parallel slots;
• applying the stencil to a substrate;
• applying a plurality of nanocomposite strips to the substrate utilizing the stencil;
• removing the stencil from the substrate;
• forming a flow layer;
• and
• coupling the flow layer to the substrate.
