    摘要: A dehydration sensor having a stable, printable, buffered-ink composition that enables one to miniaturize the detection zone and permits both buffer and indicator dye to be applied in the same area of a detection zone, without need for a conventional, large buffer pad region. The ink composition includes a weak polymeric base as its primary buffering agent.

    摘要: A lateral flow assay device for determining the relative ionic strength of urine is described. The device includes a buffering zone having a polyelectrolyte disposed therein, and an indicator zone having a pH indicator non-diffusively immobilized therein, the indicator zone being separate from the buffering zone and positioned adjacent to and in fluid communication with the buffering zone. A detection zone is part of the buffering zone, and has a buffering component comprising a weak polymeric acid and weak polymeric base with a pKa≦10−3, and a class of charged polymeric surfactants that are responsive to relative ion concentrations in a sample solution, and a charged pH indicator with a charge opposite to that of the charged polymeric surfactant. The charged polymeric surfactant is soluble in amounts of greater than or equal to about 1% by weight (≧1 wt. % solute) in water and aqueous solutions of low ionic concentration of ≦0.1 wt. % salts, but insoluble ( 0.1 wt. % salts. The present invention also describes absorbent articles incorporating such an assay device and methods of monitoring dehydration or testing ion strength of a urine sample using such a test format.
