Preservation of MCMV global virion structure after femtosecond laser irradiation. Representative electron microscopy images are shown of control and laser-irradiated virions (150 to 200 nm in diameter) at both $\mathrm{50,000}\times$ and $\mathrm{150,000}\times$ magnification, showing no clear differences in the global appearance of viral envelope and capsid structures after irradiation.
