Sensitive naked-eye detection of Hg 2+ based on the aggregation and filtration of thymine functionalized vesicles caused by selective interaction between thymine and Hg 2
We report a sensitive, selective and low-cost method for the naked-eye detection of Hg 2+ . The principle is based on rapid interaction between functionalized PDA vesicles and Hg 2+ , which leads to obvious aggregation of vesicles. Furthermore, using only a simple filtration process, without using a...

. The principle is based on rapid interaction between functionalized PDA vesicles and Hg

, which leads to obvious aggregation of vesicles. Furthermore, using only a simple filtration process, without using any other color indicator or specialized equipment, a higher detection sensitivity for Hg

(0.1 μM) than chromophoric colorimetric sensors (approximately 1–100 μM) was obtained. |
