    "abstract": "A pneumatic gun for ballistic delivery of microparticles to soft targets is\nproposed and demonstrated. The particles are accelerated by a high speed flow\nof Helium in a capillary tube. Vacuum suction applied to a concentric, larger\ndiameter tube is used to divert substantially all of the flow of Helium from\nthe gun nozzle, thereby preventing the gas from hitting and damaging the\ntarget. Speed of ejection of micron-sized gold particles from the gun nozzle,\nand their depth of penetration into agarose gels are reported.",
