| Description |
A paper based microfluidic device is fabricated that can rapidly detect
very lowconcentrations of As3+ ions using a gold nanosensor, Au–TA–
TG. This simple but efficient system develops a visible bluish-black
colour precipitate due to the formation of nanoparticle aggregates
through transverse diffusive mixing of Au–TA–TG with As3+ ions on a
paper substrate. The approach is extremely selective for arsenic with a
detection limit of 1.0 ppb, which is lower than the WHO's reference
standard for drinking water.
