Body distribution of Cy7-conjugated BP NPs compared to control NPs. Mice were injected with 100 µL of 0.1 mg/mL of NPs, were sacrificed 4 h, 1 and 7 days post injection and organs were harvested. Liver (a), Kidney (b), Intestine (c), Colon (d) and Heart (e). Spectrally unmixed, high contrast organ images were obtained and fluorescence intensity measurements of the individual organs was performed using ImageJ software
