Highly selective colorimetric sensing of cyanide based on formation of dipyrrin adducts.
Cyanide sensing has attracted increasing interest due to its toxicity and wide use in industrial activities. Herein, we developed three colorimetric cyanide sensors by the modification of the α-position of a dipyrrin chromophore with various carbonyl groups, namely, C(6)F(5)CO, C(6)H(5)CO and CHO for 1, 2 and 3, respectively. In dichloromethane, these sensors respond to both CN(-) and F(-) with...
متن کاملHighly selective colorimetric bacteria sensing based on protein-capped nanoparticles.
A rapid and cost-effective colorimetric sensor has been developed for the detection of bacteria (Bacillus subtilis was selected as an example). The sensor was designed to rely on lysozyme-capped AuNPs with the advantages of effective amplification and high specificity. In the sensing system, lysozyme was able to bind strongly to Bacillus subtilis, which effectively induced a color change of the...
متن کاملAnionic Chromogenic Chemosensors Highly Selective for Fluoride or Cyanide Based on 4-(4-Nitrobenzylideneamine)phenol
O composto 4-(4-nitrobenzilidenoamino)fenol foi utilizado em duas estratégias que permitem uma detecção altamente seletiva de F e CN. Primeiramente, observou-se que o composto em acetonitrila age como um quimiossensor cromogênico devido ao fato de que ânions básicos levam ao seu desprotonamento (solução incolor), resultando numa solução colorida contendo fenolato. A detecção seletiva de CN sobr...
متن کاملAn alternative approach to develop a highly sensitive and selective chemosensor for the colorimetric sensing of cyanide in water.
By utilizing a new indirect trick, an old and cheap compound, zincon (2-carboxy-2'-hydroxy-5'-sulfoformazylbenzene), was found to be a "novel" highly sensitive and selective chemosensor for cyanide in pure aqueous solutions, with a detection limit of 0.13 ppm and a color change that could be observed by the naked eye.
