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.

Abstract: An article comprises a structure having an outer surface extending along a longitudinal axis. At least a portion of a cross section of the outer surface is convex. Fluid control channels extend along a channel longitudinal axis along at least a portion the convex surface. The channel longitudinal axis makes an angle between 0 and 90 degrees with respect to the longitudinal axis of the outer surface. The fluid control channels are configured to allow capillary movement of liquid in the channels and across the convex surface.
