DNA–Gold Nanozyme-Modified Paper Device for Enhanced Colorimetric Detection of Mercury Ions

In this work, a paper device consisted of a patterned paper chip, wicking pads, and a base was fabricated. On the paper chip, DNA–gold nanoparticles (DNA–AuNPs) were deposited and Hg<sup>2+ </sup>ions could be adsorbed by the DNA–AuNPs. The formed DNA–AuNP/Hg<sup>2+</sup> nan...
