The method, protocol describes a technique of how subcellular-sized particles are accelerated to high velocity to carry double-stranded RNA (dsRNA) into Drosophila embryos.  The major advantage of this procedure over microinjection (Microinjection of dsRNA into Drosophila Embryos) is that particle bombardment is easier and faster to perform.  In addition, the mechanical trauma received is far less than by microinjection, allowing better survival of embryos and fewer phenotypic artifacts.
