The present invention concerns an improved optical method and optical sensing device for determining the levels of polyhydroxyl-substituted organic molecules in vitro and/or in vivo in aqueous media. The range of detection is between about 400 and 800 nm. In particular, a sensory devise is implemented in a mammal to determine sugar levels. Specifically, a dye is combined with a conjugated nitrogen-containing heterocyclic aromatic boronic acid-substituted bis-onium compound in the presence of a sugar, such as fructose or glucose. The viologens are preferred as the aromatic conjugated nitrogen-containing boronic acid substituted compounds. The method is useful to determine sugar levels in a human being.
Embodiments of this invention relate to an improved optical method and/or sensor for measuring the concentration of polyhydroxy substituted organic molecules in aqueous or organic media. In one application, the method and sensor monitor the concentration of sugars, i.e., glucose or fructose, in aqueous solution in vitro. In particular, the method and sensor are adapted to monitor the concentration of sugars, i.e., glucose or fructose, in blood while implanted intravascularly.
