A controllable staining colorimetric method based on carboxylated cellulose membranes for early-warning and semi-quantitative detection of aflatoxins in water

Abstract

The group specific assay of total aflatoxins (AFs) often requires specific antibodies. A controllable staining colorimetric method was proposed to determine AFs by exploiting controllable electrostatic-staining of carboxylated cellulose membranes...

Peroxidase mimicking activity of Saccharum officinarum L. capped gold nanoparticles using o-dianisidine as a substrate

“…3(b), peaks were observed at 3302 cm À1 , 2921 cm À1 , 1644 cm À1 , 1420 cm À1 , and 1025 cm À1 corresponding to O-H stretching, CH 2 asymmetric stretching, CQO stretching, C-H bending, and a merged band of C-O-C symmetric stretch and OH bending frequency, respectively. 30 SOLB extract is mainly composed of reducing sugars and lignin.
