Abstract
A device for delivery of particles into biological tissue includes at least one conduit and a propellant source fluidically coupled to the conduit and configured to deliver a propellant into the conduit. A particle source is configured to release elongated particles into the conduit, the elongated particles having a width, w, a length, l>w. The propellant source and the conduit are configured to propel the elongated particles in a collimated particle stream toward the biological tissue. An alignment mechanism is configured to align a longitudinal axis of the elongated particles to be substantially parallel to a direction of the particle stream in an alignment region of the conduit. The aligned elongated particles are ejected from the conduit and impact the biological tissue.
