ABSTRACT
A pneumatic gun for ballistic delivery of microparticles to soft targets is proposed and demonstrated. The particles are accelerated by a high-speed flow of helium in a capillary tube. Vacuum suction applied to a concentric larger diameter tube is used to divert substantially all of the flow of helium from the gun nozzle, thereby preventing the gas from hitting and damaging the target. Speed of ejection of micron-sized gold particles from the gun nozzle, and their depth of penetration into agarose gels are reported.

    We show that helium nanodroplets generated using a pulsed valve undergo velocity dispersion according to their size. This makes it possible to use temporal selection to probe nanodroplets of a particular size within the pulsed gas profile rather than changing the expansion conditions as is done...

    Protein kinase CK2 is emerging as a target in neoplastic diseases. Inhibition of CK2 by small compounds could lead to new therapies by counteracting the elevated CK2 activities found in a variety of tumors. Currently, CK2 inhibitors are primarily evaluated by a radiometric in vitro assay tracing...
