Scientists are trying to improve almost everything that ussurrounds, and contraceptives are no exception. Currently, women have access to various types of contraceptives from implantable implants to pills, but they are unlikely to be compared with a new development from Georgia Tech. Researchers have created a painless patch with hundreds of microscopic needles containing contraceptives. The most interesting is that the patch works for a whole month without the need for replacement.
Patches with microscopic needles thatgetting under the skin they begin to release active substances into the blood, scientists have already used to deliver insulin and even substances to break down fat in the body. In September 2018, a team of scientists from the University of Washington came up with how this technology can save people from the flu virus - instead of vaccinations, they offered to put a plaster on the skin, which painlessly injects the necessary vaccine for one day.
Needles plaster contraceptive made ofpolymers and substances called levonorgestrel - is the main component of all contraceptives. The polymers are easily destroyed in the body and during the month release the above substance, preventing unwanted pregnancy. Researchers believe that the patch is much more convenient than other contraceptives - it can be used independently, and storage does not require special conditions.
The effectiveness of the patch was tested on rats -the contraceptive effect was seen after the introduction of levonorgestrel contained in a hundred needles. Substance stored action for almost one month. Of course, a person will need a plaster with a much larger number of needles and, according to scientists, it will soon be created and tested. Perhaps in the future the effect of such a contraceptive will last six months.
Researchers understand the possible side effectspatches - for example, they can cause skin irritation. One of the authors of the study, Mark Prausnits, hopes that clinical studies will confirm their safety for people.
