Relative reactivities of a series of polycyclic carbo- and heteroaromatic compounds to sulfonation by sulfur trioxide in nitrobenzene are measured and discussed. The results show the following reactivity in decreasing order: indole, carbazole, pyrene, perylene, naphthalene, phenanthrene, benzene, benzothiophene, and dibenzothiophene.
This invention relates to enzyme-sensitive biosensors and methods and kits using the same. Specifically, the invention relates to methods, systems and kits for the detection of enzymes using the chemical shift observed in an isotope complexed to the biosensor resulting from a change in the biosensor as the result of the enzyme's activity.
