## Abstract

Diuron, a widely used herbicide, has been banned or heavily
restricted
in several countries due to its environmental persistence and toxicity
to aquatic ecosystems. Its chemical stability allows it to remain
in soil and water for extended periods, leading to long-term contamination
and potential leaching into groundwater. This is particularly concerning
because diuron has been classified as a possible human carcinogen
and exposure through contaminated water, food, or occupational contact
raises significant safety concerns. Laboratory-based instruments provide
a robust methodology for the measurement of diuron, but there is an
opportunity for electroanalytical based devices to provide an in-the-field
approach that is comparable and, in some cases, can provide enhanced
sensitivity. The low-cost and portable nature of electrochemical instruments
allows one-site analysis, removing sample transportation and storage
costs, and reducing the overall measurement time. In this perspective,
we summarize recent advances in the measurement of diuron using electroanalytical
methods, providing insights into the measurement of diuron using various
sensing materials and electrochemical platforms. A wide range of electrode
materials, such as carbon-based nanomaterials, metal nanoparticles,
and molecularly imprinted polymers, have been explored to enhance
sensitivity and selectivity in the measurement of diuron, and furthermore,
we consider the use electrochemiluminescence and additive manufacturing.
This overview highlights the role of material properties, electrode
surface modification strategies, and signal amplification to enhance
the electroanalytical detection of diuron, offering insights into
current advancements and future directions in electrochemical sensing
for environmental monitoring.
