The use of 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS) as a colorimetric and green turn on fluorescent probe for the recognition of arginine and lysine in aqueous solution is described. The limit of detection (LOD) was found to be 1.941 x 10(-6) M, whereas for Lys the LOD was 3.106 x 10(-6) M, respectively. Interestingly, the probe also shows reversibility by addition of tetrabutylammonium phosphate (TBAP). (C) 2016 Elsevier B.V. All rights reserved.
