Size-dependent lymphatic uptake of nanoscale-tailored particles as tumor mass increases
AIM: To investigate the size-dependent lymphatic uptake of nanoparticles in mice with rapidly growing syngeneic tumors.MATERIALS & METHODS: Mice were inoculated subcutaneously with EL4 lymphoma cells and on day 5 or day 6 of tumor growth, injected peritumorally with either 29 nm or 58 nm of ultra-small superparamagnetic iron oxide nanoparticles. Twenty-four hours later the animals were imaged
