Maltodextrin-based Imaging Probes (IMAGE) Georgia Institute of Technology Caption Schematic showing the chemical design of maltodextrin-based imaging probes, which have been used to detect bacterial infections in animals with high sensitivity and specificity. The probes are composed of maltohexaose conjugated to a fluorescent dye. They are internalized at a high rate by bacteria through the maltodextrin transport pathway as a glucose source.
