The effective test and the sensitivity test of the ICA for ZEN over 3 months is shown in Figure S2. During the 3 months of storage life and interval sampling detection, the red color intensity of the T lines and C lines were kept clear and had distinct effects. Meanwhile, the T lines completely disappeared at 5 ng/mL of ZEN standard, which meant that the sensitivity of the ICA was well represented in this storage life. This indicates that the developed ICA for ZEN had a desirable stability, and the useful life could be at least 3 months.
