“…The appearance of a peak for As V in the case of GNP-MMT@Eu after interaction with only As III indicates that partial oxidation of As III species occurred during the interaction process, which may be happening because of dissolved oxygen in the experimental solution. Ghosh et al reported similar results where they confirmed As V binding with Eu(III)-capped YPO 4 nanoparticles by observing the As 3d XPS peak at 46.5 eV . In another study, Chen at al.…”

“…The drawback of this system is that the detection limit of this is ∼6.0 ppm which is way higher than the WHO safe limit. 19 Below this concentration, the researcher did not find any change in the luminescence behavior of Eu III -doped YPO 4 nanoparticles. Also, none of the lanthanide-functionalized nanoparticle-based sensors are useful for on-site detection of arsenic as fluorescence measurements are required during the sensing process.…”

“…They have synthesized a Eu III -doped YPO 4 nanorod by coprecipitation method and observed the enhancement of the luminescence property of the Eu III ion in the presence of arsenate and quenching of the same in the presence of the arsenite. The drawback of this system is that the detection limit of this is ∼6.0 ppm which is way higher than the WHO safe limit . Below this concentration, the researcher did not find any change in the luminescence behavior of Eu III -doped YPO 4 nanoparticles.…”

The europium-functionalized gold nanoparticle is developed as a sensor for highly sensitive and specific detection of the very low concentration of As III and As V ions in water and using the paper strip. The GNP-MMT@Eu nanosensor is synthesized by stepwise chemical conjugations of gold nanoparticle (GNP) with 2-mercapto-4methyl-5-thiazoleacetic acid (MMT) followed by europium chloride (EuCl 3 ) in deionized (DI) water. GNP-MMT@Eu shows a visible color change in the presence of both As III and As V ions in an aqueous medium, because of arsenic-mediated aggregation through electrostatic attraction and covalent-type interaction that form an inner-sphere arsenic complex between nanoparticles, which is proportional to the concentration of arsenic. The fluorometric properties of the nanosensor are not significant, and thus, only colorimetric and spectroscopic methods that are very much selective for As III and As V ions are used with a detection limit of ≤10.0 ppb. GNP-MMT@Eu also shows excellent capabilities for regeneration and quantitative estimation of total dissolved arsenic in a real water sample, signifying the usefulness of the developed nanosensor for field-test applications such as arsenic level screening during the water quality monitoring process.

“…A lot of research is going on in the area of nanosensor development for arsenic sensing. [213][214][215][216][217][218][219][220][221][222][223][224][225][226] In this regard, a few bacterial and peptide-based biosensors exhibited bioluminescence in the presence of As(OH) 3 . Conversely, engineering of the bacteria to detect ppb levels detection has been found to be difficult.…”
