Hepatitis B virus detected in paper currencies in a densely populated city of India: A plausible source of horizontal transmission?

Figure 6 Atomic force microscopy images of sample S8 after immunoprecipitation and Triton X treatment. A and B: Typical icosahedral particles, plausibly hepatitis B virus core particles. Triton X-100 treatment followed by sonication led to partial/complete disintegration of virus envelope, thus exposing the core particles; D and E: Magnified images of the region encircled in Figure 6A and B, respectively. The arrows mark the icosahedral hepatitis B virus core particles; C and F: 3D images of the hepatitis B virus core particles seen in Figure 6B and E, respectively.
