Abstract
Plant virions, as nano-sized particles, have the advantages of high
accumulation levels in plant cells, low regeneration cost, simple purification process
and safety for the human body. They are ideal natural nanomaterials. With the
development of bio-nanotechnology, plant virus nanoparticles show more and more
applicable potential in the field of medicine. This chapter reviews the research progress
and application of plant virus nanoparticles in the field of medicine, focusing on
targeted drug delivery, molecular imaging and vaccine preparation.
