Biolistic guns to shoot nanoparticle bullets into plant cells

Abstract:
Most nanobiotechnology research today is focused on human medical applications and, mostly for testing and demonstration purposes, on animals. As nanotechnology is gaining interest with regard to agricultural applications, plant science research focusing on investigation of plant genomics and gene function as well as improvement of crop species has become a nanotechnology frontier. Plant cells differ from animal cells in several aspects, a major one being that they possess a wall surrounding them to provide, among other things, mechanical and structural support. The plant cell wall is generally made up of pollysacharides and cellulose. Cellulose provides a stiff and rigid environment for the cell to live in. Thanks to this wall, viruses have no active way of penetrating plant cells but rely on mechanical wounds or infected seeds for transmission. Researchers are commonly using surface-functionalized silica nanoparticles as nonviral nanocarriers for experimental drug and DNA delivery into animal cells but their use with plants so far was limited due to the cell wall. In a first demonstration of the utilization of porous nanoparticle materials for intracellular controlled release and gene transfer application in plants, researchers have used silica nanoparticles to penetrate the cell wall and deliver a payload into the cell.
