Detection of Mercury Ion in a Microfluidic Device Using Colorimetric Method
Abstract
The presence of toxic metal ions such as Mercury (Hg2+), Lead (Pb2+), Arsenic (As3+), Chromium (Cr3+) and
Cadmium (Cd2+) in water source leads to serious and long-standing effects on human health. In specific, this may cause
severe damages in kidney, stomachaches, dizziness, liver, anemia and neurotic disorder. Hence the detection of toxic metal
ions is necessary to prevent serious diseases. This paper presents the detection of toxic mercury ion (Hg2+) in fabricated
herringbone microfluidic chip using colorimetric method and L-Arginine (L-Arg) functionalized with synthesized gold
nanofluids (L-Arg-AuNFs) as sensing probe. Then the Hg2+ were selectively detected, 10 μM was successfully detected
using optical microscope.
