Figure 2. Morphological analysis of purified HBc core particles with Atomic Force Microscopy (AFM).

Figure 2

(A) AFM images using tapping mode AFM (TM-AFM) and (B) Histogram analysis of assembled HBc particles. HBc particles were deposited on the mica substrates and measurements were carried out in air at 25 °C, using a Bruker Dimension ICON with Scan Assist. Dis-assembled HBc were achieved by dilution in distilled water at 40 °C for 10 min. Core shell structure was observed for the assembled particles for both formulations. Histograms were obtained for n = 50, analysed using WSxM v5.0 Developed 6.2 and Origin 7.5 software. Scan size is 300 nm × 300 nm. Scale bars are 60 nm.
