Enhanced Colorimetric Signal for Accurate Signal Detection in Paper-Based Biosensors
Diagnostics, 2020 Paper-based colorimetric biosensors combine the use of paper with colorimetric signal detection. However, they usually demonstrate lower sensitivities because a signal amplification procedure has not been used.

COLORIMETRIC ASSAY OF HEXAMETHYLENETETRAMINE [PDF]
Bulletin of Pharmaceutical Sciences. Assiut, 1981 Two photometric procedures are described for the determination of hexamethylenetetramine, free and in pharmaceutical preparation. The two methods are based on color formation by the ammonia released after the hydrolysis of hexamethylenetetramine. In the first method sodium-l,2 naphthoquinone-4-sulphonate reagent was added to the hydrolyzed hexamine ...

Evaluation of beta-galactosidase activity in tissue in the presence of blood [PDF]
, 2000 The reporter gene for beta -galactosidase is frequently used to determine the efficiency of gene transfer in arteries. However, blood is often present in arterial explants and may compromise the results by the presence of hemoglobin. The light absorption
