Goodbye hypodermic needles! Scientists have been studying plaster with microneedles for many years. This plaster replaces traditional needles. Compared with hypodermic needles, patches with micro-needles are more effective, cheaper and less painful.
TEDGlobal is currently held in Edinburgh. At this conference, scientists demonstrated the latest innovative technologies. Biomedical engineer Professor Mark Kendall demonstrated on the stage how the microneedle plaster sticks to the skin. It is very special for Kendall to show Nanopatch on the Scottish stage, because the needle was born in 1853 and is only a few kilometers away.
Disadvantages of needles
Hypodermic needles make people live longer. Vaccination can prevent disease. Of course, other important innovations are clean drinking water and sewage. Injection needles still have many disadvantages. 1.3 million people die from needle injuries every year. In addition, 20% of people are afraid of acupuncture. Moreover, the needle is not as effective because the vaccine is injected into the muscle instead of the skin.
Nanopatch has thousands of tiny tiny needles that can easily deliver the vaccine to the correct cells. According to Kendall, because of the increased effectiveness, fewer vaccines are needed. Studies on laboratory animals have shown that a micropatch with a dose of 450 ng of flu is more effective than an injection needle with a dose of 600 ng of flu.
Another major advantage of Nanopatch is that the vaccine does not have to be liquid. It can be stored as dry matter. Moreover, although liquid vaccines usually have to be refrigerated. Sometimes this can cause problems, especially in developing countries.
Nanopatch is currently being tested in Papua New Guinea. If the patch with microneedles is effective, the nano patch can also be used in Europe. Not the flu shot of 2014, but the anti-flu patch?
