Various specific methods have been exercised in recent years to detect heavy metal ions in
drinking water or body fluids for environmental as well as health safety. Likewise …

A multi-metal colorimetric and fluorescent sensor based on Schiff base bearing an “ONN”-
coordination site was developed. This newly designed sensor is a highly sensitive and …

Nickel oxide film (NiO-nanoparticles) was successfully deposed onto the carbon graphite
electrode (GrE) and used as an electrochemical sensor for the detection of trace levels of …

Whether short-term or long-term, overexposure to an abnormal amount of copper ion does
significant harm to human health. Considering its nonbiodegradability, it is critical to …

A flexible electrochemical heavy metal sensor based on a gold (Au) electrode modified with
layer-by-layer (LBL) assembly of titanium carbide (Ti3C2T x) and multiwalled carbon …

The copper ion (Cu2+), as a type of essential element, plays important roles in various
metabolic processes of organisms. However, an excessive intake of Cu2+ can induce a …

Based on anodic stripping voltammetric (ASV) method, this paper demonstrated a portable
sensor system for copper ions (Cu 2+) detection in water samples. The proposed sensor …

Abstract Mercury ion (Hg 2+) has been recognized as one of the most hazardous metal
pollutants that can cause deleterious effects on human health and the environment even at …

Current potentiometric Cu 2+ sensors mostly rely on polymer-membrane-based solid-
contact ion-selective electrodes (SC-ISEs) that constitute ion-selective membranes (ISM) …

A novel ratiometric fluorescence sensor for rapid and on-site visual detection of Cu 2+ was
designed and synthesized by integrating yellow-emission rhodamine fluorophore (RL) and …
