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(2+) ions could be adsorbed by the DNA–AuNPs. The formed DNA–AuNP/Hg(2+) nanozyme could catalyze the tetramethylbenzid...
