dc.description.abstract | Indocyanine green (ICG) is a near-infrared optical dye approved by the Food and Drug Administration. ICG has been investigated as a simultaneous color and fluorescence-imaging tracer for the intraoperative identification of sentinel lymph nodes, but its use has recently expanded to include application as a photosensitizer for the local photodynamic/thermal treatment of identified lymph node metastases. The current study was designed to develop an ICG-loaded nanoemulsion as an effective agent for both the diagnosis and treatment of lymph node metastases. Incorporating the cationic lipid stearylamine (SA) together with ICG in the shell of nanoemulsions did not affect the loaded ICG concentration, but changed the surface charge of nanoemulsions from a negative to a positive value and improved the physical stability of nanoemulsions. Loading ICG into SA-incorporated nanoemulsions more effectively blocked the aggregation and degradation of ICG compared to loading in SA-free nanoemulsions. SA incorporation also enhanced tumor cell uptake of ICG-loaded nanoemulsions, resulting in greater cell killing upon light irradiation. After subcutaneous injection into the footpad of mice, SA-incorporated nanoemulsions increased the concentration of ICG accumulated in popliteal lymph nodes to a greater extent than SA-free nanoemulsions without affecting the kinetics of lymph node uptake of nanoemulsions. These multiple beneficial effects of incorporating SA in nanoemulsions are likely attributable to the electrostatic interaction between anionic ICG and cationic SA, as well as the change in the nanoemulsion surface charge from negative to positive. Our findings indicate that SA-incorporated nanoemulsions are promising ICG carriers for combined diagnosis and treatment of lymph node metastases. | - |
