In vitro cell characterization of lipid PFCE-FETRIS nanoemulsion labeled cells. a Unhindered proliferation via cell counts in RAW cells post-exposure to lipid-PFCE-FETRIS nanoemulsion, where cell counts are normalized to the media-treated control. Control nanoemulsion consists of PFCE without FDK or Fe(III). Unpaired t-test indicates no significant difference between groups, p = 0.46. b R1 and c R2 relaxation rates show persistent relaxation enhancement in PFCE-FETRIS nanoemulsion-labeled RAW cells (After) as referenced to FETRIS-free nanoemulsion (Before). Two formulations of lipid-PFCE-FETRIS nanoemulsion were tested, i.e., 5 (FETRIS A) and 7.5 (FETRIS B) % FDK, both Fe(III) saturated. Error bars are standard deviation of the mean (N = 3).
