Ultrasensitive colorimetric detection of fluoride and arsenate in water and mammalian cells using recyclable metal oxacalixarene probe: a lateral flow assay.

ABSTRACT: Globally 3 billion people are consuming water with moderately high concentrations of fluoride and arsenic. The development of a simple point of care (PoC) device or home device for the detection of fluoride/arsenic ensures safety before consuming water. Till date, lateral flow assay (LFA) based PoC devices can detect nucleic acids, viruses and diseases. An aluminium complex of rhodamine B functionalized oxacalix[4]arene (L) was designed to execute the LFA-based PoC device. Initially, Al³⁺ and Fe³⁺ ions were involved in complexation with the rhodamine B functionalized oxacalix[4]arene (L), resulting C₁ (L-Al³⁺) and C₂ (L-Fe³⁺) complexes respectively. The receptor L, as well as the probes (C₁, C₂), were c
