Abstract: The present invention provides method of detecting a predetermined biological activity. The method includes using an aqueous mixture comprising a first indicator reagent with a first absorption spectrum and a second indicator reagent. The second indicator reagent is converted by the predetermined biological activity to a second biological derivative with a second emission spectrum. The first absorbance spectrum includes detectable absorbance in at least a portion of wavelengths present in the second emission spectrum. The first indicator reagent is received and concentrated from an aqueous liquid by a substrate, facilitating the detection of the second biological derivative.
