Abstract
In many regions of the world, drinking water has been contaminated with arsenic, resulting in a serious public health crisis and posing a threat to global sustainability. Therefore, the detection of arsenic in contaminated water has received considerable attention from the research community. The unique properties of nanomaterials can be harnessed by incorporating them into sensors that may improve their sensitivity, selectivity, reproducibility, and portability. This article highlights the recent advances in nanomaterials-based sensors for the detection of arsenic in contaminated water. The various sensing techniques and their applications in nanomaterials-based sensing are presented. The future direction toward a lab-on-a-chip (LOC) device for sensing real-world samples is also outlined.
