Fluorescence sensing of arsenate at nanomolar level in a greener way: naphthalene based probe for living cell imaging

Abstract

Naphthalene–salisaldehyde conjugate (NAPSAL) is established as a novel arsenate (H2AsO4) selective ‘turn-on’ fluorescence probe. It can detect as low as 5 × 10−9 M H2AsO4 in HEPES buffered EtOH : water (0.1 M, 1 : 9, v/v, pH 7.4). Trace level H2AsO4 in drinking water samples is measured using standard addition method. Intracellular arsenate in Candida albicans, grown in arsenic contaminated water of Purbasthali has successfully been detected under fluorescence microscope.
