Fig. 2. Characterization of 3D self-assembled serpentine nanostructures. (a) SEM image of large scale continuous serpentine nanostructures without any cracks and defects. (b) Amplified SEM image showing the uniform close packing of beads on nanostructures. (c) Quantification of immobilized anti-CD81 antibodies on ExoProfile chip with FITC-labeled anti-IgG antibody and (d) BSA negative control.
