Characterization of nanoparticles
The morphology of NPsA/siRNA/PTX, NPsB/siRNA/PTX and NPsAB/siRNA/PTX
nanoparticles were examined using transmission electron microscopy (TEM,
JEM-2100).
The average size, zeta potential and magnetic properties of
nanoparticles were investigated using dynamic light scattering (DLS,
Malvern Instruments, Westborough, MA, USA) and vibrating sample
magnetometer (VSM, a Standard 7403 Series, Lakeshore) respectively.
