Visual fluorescent responses of the developed test strips to different metal ions with the images taken under UV light.

(a) Fluorescence intensity changes of the developed test strips in the presence of different metal ions (3.0 μM) alone. (b) Fluorescence intensity changes of the developed test strips for Hg2+ ions separately co-existing other metal ions (3.0 μM) indicated.
