The development of injection options would be possible thanks to a 3D printer.

The technology on the health side, as it has been developed, is a patch made via a 3D printer that could in the future become a vaccination option that exhibits better functionality than normal injections.
The researchers first tested the patch on mice to see how well the vaccine transferred and to see how the immune system responded.
Evaluation showed that T lymphocytes and antibodies induced by the vaccine reached concentrations between 10 and 50-fold higher in the blood after immunization with the patch. Compared with hypodermic injection Classic.
The vaccine, in its early stages, carried out in experimental animals with model components, yielded good results and strengthened the immune system, surpassing the efficacy of an injection with conventional needles, described by the team of doctors and nanoengineers who explored will do. demonstrated that this system would also save vaccines as a lower concentrated dose would suffice.
This patch, adhered to the skin for a period of time, inoculates the body through this printed patch, which consists of microneedles, precisely aligned into a polymer base and the right diameter to penetrate the surface of the skin. Huh. Thus being considered as a painless version with an autonomous application, as it can be applied without the need of going to a specialist.
The scientific team, led by Joseph M. DeSimone of Stanford University, hopes to result in improved production Due to advances in 3D printing, patches soon become available for application.
The system tested with model vaccine components could easily be turned into a vaccine against COVID-19, influenza, measles or hepatitis, say the study authors, who also illustrate that research microneedle patch system As a technological innovation, it has been happening all over the world for some time, opening up the possibility of better results in the future.
