Pollution due to heavy metals is becoming increasingly hazardous; therefore, demand for
the large-scale deployment of sensor nodes for water quality monitoring has increased. The …

This study demonstrated a simple and reliable method to rapidly detect Pb2+ in aqueous
solution, exploiting gold nanoparticles as a lead ion probe; the results indicated that the dual …

A compact, durable, low-reagent-usage, portable miniaturized electrochemical sensor is
successfully developed for the high sensitivity detection of trace lead. We fabricated …

Graphite pencil lead (GPL) covered with Au nanodendrites (AuNDs)(the AuND@ GPL
sensor) has been demonstrated as an electrochemical sensor for simultaneous detection of …

This paper presents a reusable polymer lab chip sensor for continuous and on-site heavy
metal monitoring in nature. In particular, detection of lead (Pb (II)), which is the most common …

A fully automated portable analyzer for toxic metal ion detection based on a combination of a
nanostructured electrochemical sensor and a sequential flow injection system has been …

In this study, nanoporous gold (NPG) was deposited on a screen-printed carbon electrode
(SPCE) by the dynamic hydrogen bubble template (DHBT) method to prepare an …

Heavy metals in drinking water have become a severe threat to human health. Detection of
heavy metals has been achieved by electrochemical sensors that are modified with complex …

A nanoporous gold microelectrode (NPG-µE) was fabricated and used for Pb (II) detection in
seawater samples via square wave anodic stripping voltammetry (SWASV). The Au …

Water is a precious resource that is under threat from a number of pressures, including, for
example, release of toxic compounds, that can have damaging effect on ecology and human …
