For a long time, scientists around the world tried to finda way to "make" the pill move in the right direction in the human body without resorting to various tricks, such as a magnetic field, microbots, and so on. And finally, it was possible to a group of researchers from the United States. They not only came up with a way to do their plan, but also used a very interesting technology for this.
According to the editors of ACS Nano, forThe development is in charge of a team of researchers from the University of California at San Diego. Their new invention in pharmacy is somewhat similar to the operation of a turbine, only in a significantly reduced form. They are multilayer spherical particles about 20 micrometers in size. Magnesium molecules coated with a layer of titanium dioxide and a 100-nanometer layer of maltose and lactose act as a nucleus. The latter is needed in order to protect the structure and ensure its adhesion to the walls of the stomach or intestines when necessary. In addition, the particle contains PLGA - polylactide co-glycolide, which is the carrier of the drug.
Prior to this technology test,some years. Once in the digestive tract, magnesium begins to work as a fuel, directing the particle to where it is needed. By adjusting the amount of magnesium, it is possible to achieve different "range of motion" and accordingly calculate the places where the particle stops and starts to act. In laboratory animal studies, a luminous dye was used instead of the drug, the delivery of which could be observed in real time. The experiment was successful and now scientists are starting to work on cheaper technology.
