words only definitions & notes
  1. erbium
    a trivalent metallic element of the rare earth group
    The device uses an erbium-doped yttrium aluminum garnet, or Er:YAG, laser, to drive a tiny, precise stream of liquid drug with just the right amount of force.
  2. nanometer
    a metric unit of length equal to one billionth of a meter
    In this latest version, described in the study, the team used a laser with a wavelength of 2,940 nanometers.
  3. transdermal
    through the unbroken skin
    Painless microjet injections powered by laser could one day replace jabs from hypodermic needles in delivering annual flu shots, vaccines and other medications, according to researchers at Seoul National University in South Korea, who write about the desi
  4. yttrium
    a silvery metallic element that is common in rare-earth minerals; used in magnesium and aluminum alloys
    The device uses an erbium-doped yttrium aluminum garnet, or Er:YAG, laser, to drive a tiny, precise stream of liquid drug with just the right amount of force.
  5. hypodermic needle
    a hollow needle
    Painless microjet injections powered by laser could one day replace jabs from hypodermic needles in delivering annual flu shots, vaccines and other medications, according to researchers at Seoul National University in South Korea, who write about t
  6. wavelength
    a way of thinking or coming to mutual understanding
    For instance, in previous versions, the laser wavelength was not quite right in that it was not well absorbed in the driving liquid, and did not produce a good vapor bubble capable of delivering the right amount of elastic strain to the membrane.
  7. epidermal
    of or relating to a cuticle or cuticula
    But just the fact they are aiming for the epidermal layer just under the surface of the skin, about 500 micrometers down, where there are no nerve endings, should already ensure it is "completely pain-free".
  8. tensile strength
    the strength of material expressed as the greatest longitudinal stress it can bear without tearing apart
    Yoh explains that the jet pressure is higher than the tensile strength of skin, so it penetrates smoothly into the targeted depth underneath, causing no splashback.
  9. hypodermic
    a piston syringe that is fitted with a needle for injections
    Painless microjet injections powered by laser could one day replace jabs from hypodermic needles in delivering annual flu shots, vaccines and other medications, according to researchers at Seoul National University in South Korea, who write about the design of their Er:YAG laser microjet transdermal device and how they tested it on guinea pigs in the 15 September issue of Optics Letters.
  10. guinea
    a former British gold coin worth 21 shillings
    Painless microjet injections powered by laser could one day replace jabs from hypodermic needles in delivering annual flu shots, vaccines and other medications, according to researchers at Seoul National University in South Korea, who write about the design of their Er:YAG laser microjet transdermal device and how they tested it on guinea pigs in the 15 September issue of Optics Letters.
  11. jab
    poke or thrust abruptly
    Painless microjet injections powered by laser could one day replace jabs from hypodermic needles in delivering annual flu shots, vaccines and other medications, according to researchers at Seoul National University in South Korea, who write about the design of their Er:YAG laser microjet transdermal device and how they tested it on guinea pigs in the 15 September issue of Optics Letters.
  12. penetration
    the act of entering into or through something
    "The laser-driven microjet injector can precisely control dose and the depth of drug penetration underneath the skin.
  13. aerospace
    the atmosphere and outer space considered as a whole
    It uses multiple pulses of laser beam at lower energy, thereby delivering a significantly higher dose than a previous version, the Nd:YAG system, report senior author Jack Yoh, professor of mechanical and aerospace engineering, and colleagues.
  14. piston
    mechanical device that has a plunging or thrusting motion
    Other researchers have tried to develop similar microjet systems as that devised by Yoh and colleagues, but they are invariably mechanically powered, using piston-based methods to drive the drugs into the skin.
  15. garnet
    any of a group of hard glassy minerals used as gemstones
    The device uses an erbium-doped yttrium aluminum garnet, or Er:YAG, laser, to drive a tiny, precise stream of liquid drug with just the right amount of force.
  16. facial
    of or concerning the front of the head
    The type of laser in their device is commonly used by dermatologists, particularly for facial cosmetic treatments.
  17. colleague
    an associate that one works with
    It uses multiple pulses of laser beam at lower energy, thereby delivering a significantly higher dose than a previous version, the Nd:YAG system, report senior author Jack Yoh, professor of mechanical and aerospace engineering, and colleagues.
  18. Seoul
    the capital of South Korea and the largest city of Asia
    Painless microjet injections powered by laser could one day replace jabs from hypodermic needles in delivering annual flu shots, vaccines and other medications, according to researchers at Seoul National University in South Korea, who write about the design of their Er:YAG laser microjet transdermal device and how they tested it on guinea pigs in the 15 September issue of Optics Letters.
  19. penetrate
    pass into or through, often by overcoming resistance
    Yoh explains that the jet pressure is higher than the tensile strength of skin, so it penetrates smoothly into the targeted depth underneath, causing no splashback.
  20. motor neuron
    a neuron conducting impulses outwards from the brain or spinal cord
