Researchers have developed as a subtle endoscope that it can be used to visualize blood vessels of mice.

With the help of a 3D printer, a group of scientists from the University of Adelaide and Stuttgart University printed complex camera lenses at the end of the fiber thinner thinner of the human hair. Although lenses are so small that they are impossible to see the naked eye, but they have very high quality.

According to the team, the thickness of the endoscope in the protective casing does not exceed 0.5 mm, which makes it the most subtle of such devices today. Small size and high-quality lenses allow doctors to observe the formation and development of cholesterol plaques from the inside of vessels, helping to study the main factors of various diseases.

In the future, the device will help improve the diagnosis, understanding the causes of heart disease and blood vessels, therefore, the methods of their treatment and prevention.
