Technology:
Teijin developed a tiny
needle that replaces the traditional metal needle. As the photo shows, they are
lined on the surface of a sheet for medication. Each of them is finer than the
sting of a mosquito, and does not create any pain even though it stabs in the
skin. In addition, it will melt in the body even though it is broken inside the
body. The experiment that uses human bodies will start in 2016, and the new
product is expected to be a commercial reality in 2020.
(Photo) Teijin's newly-developed tiny needles made of biodegradable polyester.
The tiny needle is
0.02-0.03 mm thick and less than 1.0 mm long. Drugs and vaccines applied on the
surface of the tiny needle filter into the human body. Made of biodegradable polyester,
it resolves inside the human body over time even though it is broken inside the
human body. The experiment that uses mice has already begun. It is hard to
react with a drug because they are made of biodegradable polyester.
Accordingly, efficacy of the drug applied on it does not deteriorate even
though treated needed is stored for a long period. It can be produced at a
lower cost than the metal needle, and it does not create any anxiety over
allergy.
