& # 39; Superdogs & # 39; crime prevention with built-in night vision can someday be created because scientists claim that an injection with nanoparticles can offer animals the possibility of seeing infrared light
- Scientists have successfully given mice the opportunity to see near infrared light
- An injection with nanoparticles increases the natural range of an animal's vision
- It took ten weeks and scientists say it could then be tested on dogs
- Researchers say that police officers can project a pattern onto the body of a lawbreaker from a distance and the dog can catch them without disturbing other people
Superdogs with infrared night vision can soon be made and used to chase criminals.
Scientists have successfully given mice the opportunity to see infrared wavelengths of light for up to ten weeks thanks to an injection of nanoparticles into their eyes.
Scientists now say that dogs can be the next step, where people are the ultimate goal if the safety of the procedure can be guaranteed.
"If we had a super dog that could see near infrared light, we could project a pattern onto the body of a lawbreaker from a distance, and the dog could catch them without disturbing other people," Dr. said. Han from the University of Massachusetts Medical School. .

Night vision is already an essential part of equipment for soldiers, spies and science fiction heroes, but the injection with nanoparticles can give animals the opportunity immediately.
The researchers discovered that the chemicals gave mice the ability to see more wavelengths of light than they can naturally.
The results are (presented this week at the American Chemical Society (ACS) Fall 2019 National Meeting & Exposition.
& # 39; Looking at the universe, we only see visible light & # 39 ;, says Dr. Gang Han, the lead investigator of the project.
& # 39; But if we were to see near infrared, we could see the universe in a whole new way.
& # 39; Maybe we can do infrared astronomy with the naked eye, or have night vision without large equipment. & # 39;

Most mammals can only detect light with wavelengths between 400 and 700 nanometers (nm).
Near infrared (NIR), on the other hand, has longer wavelengths – 750 nm to 1.4 micrometers.
Upconversion nanoparticles (UCNP & # 39; s) were injected into their eyes containing the rare earth elements erbium and ytterbium.
They can convert energy-efficient photons from near-infrared light into green light with a higher energy that mammalian eyes can see.
To determine if the injected mice could see NIR light and process it mentally, the team performed various physiological and behavioral tests.
For example, in one test the researchers placed the mice in a Y-shaped water tank.
One branch of the tank had a platform on which the mice could climb to escape from the water.
The researchers trained the mice to swim towards visible light in the shape of a triangle that marked the escape route.
A similarly lit circle marked the branch without a platform. The researchers then replaced the visible light with NIR light.
& # 39; The mice with the particle injection could clearly see the triangle and swim towards it every time, but the mice without the injection could not see or tell the difference between the two forms & # 39 ;, says Dr. Han.
The success of the injections lasted ten weeks, but the researchers say that improving safety is paramount before it can be used in humans.
WHAT ARE THE USES OF RARE EARTH METALS?
Rare earth metals, including Yttirium, are used in various ways in the technology sector.
Most of their applications focus on building and developing high-end technology.
Yttirium – This metal element is named after a Swedish city (Ytterby) where it was first discovered in the 18th century.
Yttrium oxide is the largest use of the element.
The oxide, as well as yttrium vanadate, are used with europium to make phosphors to create the red color in television tubes.
It is used in lasers that can cut metals and in white LED lamps.
Yttrium oxide is added to the glass that is used to make camera lenses to make them heat and shock resistant. It is also used to make superconductors.
Europium – Named after the continent on which it was discovered _Europe – this element has specialized applications.
It is not only used in the production of the red color in televisions, but can also be used to make quantum memory chips to store information.
Europium is also used for printing euro banknotes. It glows red under UV light and counterfeits can be detected due to the lack of this red glow.
Energy-efficient lamps contain a little europium to give a more natural light, by balancing the blue (cold) light with a little red (warm) light.
Terbium – This element was also discovered in the Swedish quarry in Ytterby.
An alloy of terbium, dysprosium and iron lengthens and shortens in a magnetic field.
This unusual property forms the basis of loudspeakers that are placed on a flat surface, such as a window, which then acts as a loudspeaker.
Dysprosium – Dysprosium is also used in control rods of nuclear reactors.
It easily absorbs neutrons and does not swell or contract when bombarded with neutrons for long periods of time.
Dysprosium is resistant to demagnetization at high temperatures.
Demagnetization is the process by which magnetic features are removed from an object.
This makes its alloys ideal for use in permanent magnets for engines, electric vehicles, generators and wind turbines.
