Fluorescence nanotomography using resonance energy transfer: demonstration with a protein-sugar complex

Abstract
A new approach to structural sensing, fluorescence resonance energy transfer nanotomography, which interprets fluorescence decay measurement in terms of site density analysis of molecular distributions, has been applied to a glucose sensor based on competitive binding with malachite green labelled dextran to the sugar binding protein concanavalinA labelled with allophycocyanin. Opportunities for structural sensing in clinical medicine are highlighted.
