Electronic cigarettes – devices that have diversified the life of smokers around the world. They appeared on the market in 2004 and recently have been replacing the classic nicotine products. Koristilo the device heats the liquid, turning it into steam. Couples may or may not contain nicotine and, according to many, is more secure than conventional cigarette smoke. That is why most those who are planning to quit Smoking, buy vapers. But is it safe to smoke electronic cigarettes is actually?
How the study was conducted?
The researchers-chemists from UConn (Western Connecticut state University) have conducted studies, which proved that the PVS are not so harmless for our health. Moreover, the researchers came to the conclusion that electronic cigarettes are potentially much more dangerous to the human DNA than non-filter cigarettes.
To conduct research, the chemists used a cheap additive technique. They designed and printed a little 3D photofluorograph, which can monitor the degree of DNA damage. Also, the device is able to detect genotoxicity in environmental samples. DNA damage is dangerous because it causes mutations at the cellular level, leading to the development of cancer.
Many people use vaporizer just because I believe in their innocence. But the results are the UConn refute this. Using 3D-printed photofluorograph, scientists can for 5 minutes to say how the cells are damaged DNA caused by chemical substances included in the composition of Smoking liquids.
3D-printed photofluorograph equipped with micropumps, which force the liquid sample through the special holes. They come pre-loaded with the metabolic enzymes of man and his DNA. Metabolites that can cause DNA damage, fall into the hole. Any reaction between the metabolites and the DNA generates light over by the camera.
The researchers extracted tobacco smoke using artificial inhalation equipment to sample a couple of vaper. Electronic cigarette connected to the pipe with a cotton swab. On the other side thereof and the syringe and took a sample smoke.
The samples were collected in the 20, 60 and 100 simulated puffs of conventional and electronic cigarettes. Chemists from UConn was surprised by the results of the studies: potential damage to cell DNA increases with the number of puffs. It turned out that vaporizer as dangerous as conventional nicotine products.
Head of research group-UConn notes the use of additive technologies in process of creating photofluorograph. The use of 3D printing has reduced the cost of the device to a minimum.
