JUNE ALMEIDA-2

•In 1967, Almeida collected the samples and attempted to visualise them using a microscope,through a technique called electron microscopy.
•An electron microscope blasts a specimen with a beam of electrons and then records the particles’ interactions with the specimen’s surface. Since electrons have much shorter wavelengths than light, this shows scientists an image with much finer, smaller detail.
•She was able to visualize the virus by introducing it to antibodies. The virus latched itself on to the antibodies, and its structure could then be seen using negative staining—where the background is strained, leaving the specimen untouched and, therefore, visible.
