| Summary: | Accumulation of heavy metal in the environment becomes a health hazard
because of their persistence, bioaccumulation and toxicity to plants, animals and
human beings. Paper is increasingly accredited as a user-friendly and prevalent
substrate for construction of microfluidic devices. Microfluidic paper-based analytical
devices (μPADs) provide a substitute technology for development of economical,
movable, disposable and low-cost diagnostic tools for improving point of care tests
(POCTs). Hence, this microfluidic paper-based analytical devices (μpads) for rapid
detection of iron metal in agricultural soil has reported LOD and LOQ as low as 5 ppm
and 15 ppm for μpads analysis and 0.2 ppm and 0.6 ppm for UV/Visible spectroscopy.
Calibration curve with linear range of 0.5 to 8 ppm for μpad and UV/Visible
spectroscopy obtained |
