Virus particles can be visualized with which of the following?

Question

Quizplus · Accepted Answer

Negative staining of virions with electron microscopy is a common technique used to visualize virus particles. The negative staining method allows visualization of the virus particle morphology and size by creating a contrast between the background and the specimen. This technique involves staining the specimen with a heavy metal salt, which forms a negative image of the virus particle. X-ray diffraction is not commonly used for visualization of virus particles, and positive staining with cryoelectron microscopy or x-ray diffraction is not commonly used. Negative staining of infected cells with electron microscopy is also a method used to visualize virus particles, but it is less common than negative staining of virions.
