Thanks @carloserp-2000 You know for every discovery ,there are always testing phases. First, the new discovery must be tested on animals before they are used on humans.

So far, the prototype was tested on animal, pig which had a lot of similarity with human system and it worked and yielded positive results.

The final

The next phase is to test it on humans, but the little challenge is the size, which is quite a little big to be ingested for now, currently, work is on going in reducing the size further so that it will be fully applied to clinical use.
