Over the past two decades, several fluorescent sensors for iron (III) have been reported. However, the currently known fluorescent sensors that are capable of cellular iron imaging are largely limited to “turn-off” type, providing useful information but suffering from poor sensitivity, or interference from other metal ions. We have been developing rhodamine based turn-on fluorescent sensors. Here we report a new iron (III) sensor , Rh-PK, which is stable in low pH's and is capable of detecting basal level Fe+3 in the human live cells at subcellular resolution.youtubeen-USCopyright the Author(s)http://creativecommons.org/licenses/by-nc-sa/3.0/ChemistryInvestigative TechniquesTranslational Medical ResearchPoster Abstracthttps://escholarship.umassmed.edu/cgi/viewcontent.cgi?article=1203&amp;context=cts_retreat&amp;unstamped=1https://escholarship.umassmed.edu/cts_retreat/2014/posters/36069810cts_retreat/2014/posters/3
