Application of PEI-Modified Magnetic Nanoparticles as Gene Transfer Vector for the Genetic Modification of Animals
Figure 1
SEM images of magnetic nanoparticles and nanoparticle/DNA complexes: (a) SEM image of magnetic nanoparticles. The SEM image shows the spherical shape of the magnetic nanoparticles with diameter about 150 nm. (b) SEM image of nanoparticle/DNA complexes. The nanoparticle/DNA complexes are also spherical but with rougher surface. The diameter of the complexes is about 200 nm.
