Viral detection by electron microscopy: past, present and future
Standard light microscopes allow us to see our cells clearly. However, these microscopes are limited by light itselfas they cannot show anything smaller than half the wavelength of visible light – and viruses are much smaller than this. But we can use microscopes to see the damage viruses do to our cells. We … See more An indirect way of visualising viruses is to use antibodies (much like the ones your body makes in response to infection) to tag viruses with fluorescent molecules that give off light when … See more Recent advances in fluorescent microscopy have led to the development of super resolution microscopy, which combines very clever physics with computational methods to produce clear images that reveal … See more Crystallographyallows us to view structures in even more detail, at the atomic level. To do this, you need a really pure sample of virus (with no debris) suspended in … See more None of the techniques mentioned so far are able to directly visualise virus particles. That’s where electron microscopy comes in, as it can produce images at the nanometre scale.
