Test strip with sterically immobilized dyes for 0013 in accordance with an internally fluorometric assay of anions, in particular of fluoride, from aqueous matrices

摘要

Fluorescent probe for the detection of an anion, in particular of fluoride from organic, mixed aqueous - organic or organically - an aqueous and / or from an aqueous solution comprising a bodipy - core and a amido thio urine substance derivative - radical. Test strip comprising nitrocellulose for the detection of fluoride inside and outside of the laboratory, comprising a section of the impregnated with the fluorescent probe, and according to preferred embodiments, adjacent thereto, has a portion of the with a reference - dye is impregnated, which no specific interaction with fluoride, for the internal referencing, wherein a fluorescent property of the fluorescent probe in response to a of the probe is complexed fluoride measurable alteration. A method comprising the use of the fluorescent probe with a test strip or a as a solid phase support, which acts in combination with a portable reading device, in particular a ‘ laterally - flow ’ fluorescence - scanner. Nitrocellulose comprising a fluorescent probe of the type described.
