The scientists reported that they were able to track the movement of titanium dioxide nanoparticles, which
Using specialized techniques, we found evidence that particles canfrom the lungs to the placenta and possibly to fetal tissue.The placenta does not protect the nanoparticles and neither do the lungs.

Most nanoparticles are created artificially.They are used in thousands of different products, from sunscreens to pharmaceuticals to sports equipment. Nanoparticles can improve the effectiveness of drugs and the durability of products.
During the experiment, the scientists also foundtitanium dioxide in a control group of rats that were not allowed to inhale the nanoparticles. It turns out that the food given to the animals contained titanium dioxide. As a result, the researchers were able to observe the path that the nanoparticles took through the body of the rat.
According to the researchers, there is a theory thatmothers giving birth to low birth weight babies may have inhaled harmful nanoparticles. The result is inflammation that can affect body systems, such as blood flow in the uterus, which can interfere with the growth of the fetus.
