Fig. 6From: Efficient siRNA delivery and gene silencing using a lipopolypeptide hybrid vector mediated by a caveolae-mediated and temperature-dependent endocytic pathwayDetailed structure and morphology of free siRNA, mTat/PEI/siRNA, INT/siRNA and mTat/PEI/INT/siRNA by AFM. AFM images: height image, 3D image, amplitude image, and cross-section analysis (left to right) of the complexes. The frames of height images and amplitude images are 1 × 1 µm2. Scale bars are 100 nmBack to article page
