pH-sensitive dye - FAQS.TIPS

Is there a pH-sensitive dye which only show it's color in low pH environment??

Actually I'm not looking for pH indicators, but a fluorescence dye which would show its color under low-pH environment. We're trying to see if it's possible to coat such dye on molecules and let macrophages ingest them. When macrophages try to lyse it, the low-pH would induce the dye to radiate.
