A team of researchers at
Seoul National University in South Korea, is revolutionizing the way vaccines
are done today, as well as all other treatments that require an injection.
In particular, South Korean
scientists have found a way to use laser instead of the needles used today, a
painful and discomfort procedure.
According
to Yoh Jack, head of the research team, "The laser sends tiny beads of
drugs directly into the skin, using as much force as necessary, and the pain
that the patient gets, feels like the gentle blow of air to the face".
However,
this technology will not be used for the first time, as it is commonly used by dermatologists for aesthetic facial therapies, combining
the
laser with
a small adapter
that contains
the drug in
a liquid form, and a
water chamber acting as a drug "guide" .
Each laser pulse, lasting only 250 millionths of a second, creates a bubble inside of the drive fluid. This bubblr pressure forces the drug to eject from a narrow jet diameter of only 150 millionths of a meter (microns), that is slightly bigger than the
width of
a human hair.
Tests made in guinea pigs showed that with the use
of this technology the drug penetrates up to several millimeters below the skin surface. As
a result, there is no tissue damage and due to jet’s narrowness and speed, there may be little
or no pain caused.
