Antimatter has always been a topic of fascination for scientists and the general public alike due to its mysterious nature. Antimatter is the opposite of normal matter, having the same mass but opposite charge. When matter and antimatter meet, they annihilate each other, releasing an enormous amount of energy, making antimatter a potentially powerful source of energy. In the present day, however, there are no practical uses, and scientists are still trying to harness the power of antimatter. But, there are still some practical uses of antimatter that are being used today. Let’s discuss them one by one.
Medical Imaging
You already know that PET scans use antimatter for medical imaging. PET scans are used to diagnose a wide range of diseases, including cancer and heart disease. The process involves injecting a small amount of radioactive tracer material into the patient’s body, which emits positrons. The positrons then collide with electrons in the body, annihilating each other, which releases gamma rays. These gamma rays are detected by the PET scanner, which then creates a 3D image of the patient’s body.
This technology is widely used, and approximately two million PET scans are carried out each year in the United States alone. Apart from PET scans, antimatter is also used in other medical imaging techniques. For example, xenon-133 is a radioactive isotope that emits positrons and is used in single-photon emission computed tomography (SPECT) imaging.
Cancer Treatment
Antimatter can also be used in radiotherapy to treat cancer. In radiotherapy, high-energy particles, such as gamma rays, are targeted at cancerous cells to destroy them. Antimatter, specifically anti-protons, can also be used for this purpose.
Anti-protons can be made using particle accelerators and can be used to deliver a high dose of energy to cancer cells while minimizing damage to healthy cells. This technique is still in the experimental stage, and it is only used in a few facilities worldwide.
Astronomy
Antimatter can be used to study the universe as well. For example, astronomers use gamma ray telescopes to study the gamma rays produced by antimatter annihilation. These gamma rays are a powerful tool to study celestial objects, such as black holes and supernovae.
In addition, antimatter can also be used in space propulsion systems. Traditional rocket propellants use chemical reactions to generate thrust, but they have a very low specific impulse, limiting the maximum speed of the rocket. On the other hand, antimatter propulsion systems can theoretically generate much higher specific impulses, making interstellar travel a possibility. However, this technology is still in the early stages of development.
Cosmetics
Antimatter can also be used in cosmetics! Many popular skincare products use nanoparticles of silver, which are antimicrobial and can help to kill bacteria on the skin. However, antimicrobial silver nanoparticles are not the same as antimatter; instead, they are just small clusters of silver atoms.
Conclusion
The practical uses of antimatter might be limited in the present day, but we have already found some ways to use it to improve our daily lives. From medical imaging and cancer treatment to astronomy and cosmetics, antimatter has already found its way into a variety of industries. Scientists are also exploring some of the more theoretical uses of antimatter, such as interstellar travel, which could revolutionize the future of human space exploration.
While we are still a long way from unlocking the full power of antimatter, these practical uses are a great start. If we continue to explore its potential, who knows what kind of breakthroughs we could achieve in the future.
