    摘要: The present invention relates to a method of producing a structure of etch-resistant polymer on a substrate. A layer of sterol capable of polymerizing to form this structure is first deposited on a face of the substrate. Then, a first region of the layer of sterol is exposed to an electron beam to locally polymerize this layer and form the structure of etch-resistant polymer. A second region of the layer of sterol that has not been exposed to the electron beam is removed to leave. on the face of the substrate only the structure of etch-resistant polymer. Finally, a region of the face of the substrate not covered by the structure of etch-resistant polymer can be etched away, and the structure of etch-resistant polymer removed following this etching.

    摘要: The present invention relates to a method and device for needleless injection of a liquid substance in the skin or other target tissue of a patient, in which droplets of the liquid substance are produced, and the droplets of liquid substance are directed toward the surface of the patient's skin or other target tissue at a velocity sufficiently high to inject the droplets of liquid substance in the patient's skin or other target tissue. According to an illustrative embodiment, the droplets of the liquid substance are accelerated toward the surface of the patient's skin or other target tissue in order to inject the accelerated droplets of liquid substance in the patient's skin or other target tissue. According to another illustrative embodiment, a high velocity jet of gas is produced, droplets of the liquid substance are produced and supplied in the high velocity jet of gas, the droplets of liquid substance are conveyed within the high velocity jet of gas, and the high velocity jet of gas is guided toward the surface of the patient's skin or other target tissue in order to inject the conveyed droplets of liquid substance in the patient's skin or other target tissue.
