Figure 4. Comparison of biodistribution and tumor accumulation of targeted and non -targeted NPs with similar biophysicochemical properties.
(A & B) Fluorescence intensity of Alexa-488 labeled targeted NPs associated with LNCaP cells (A) and macrophages (B) normalized by that of non-targeted NPs. Blue and red bars indicate non-targeted and targeted NP formulations, respectively, selected for in vivo studies. (C) Biodistribution and (D) tumor accumulation of a targeted NP composed of 14 mol% PLGA-PEG-LIG and non-targeted NP. **Statistically significant by t-test with p < 0.005. Error bars denote ±S.D.
