Antimatter is a material composed of so-called antiparticles. It is believed that every particle we know of has an antimatter companion that is virtually identical to itself, but with the opposite charge. ... When a particle and its antiparticle meet, they annihilate each other – disappearing in a burst of light.

Step-by-step explanation:

Antimatter is used in medicine.

PET (positron emission tomography) uses positrons to produce high-resolution images of the body. Positron-emitting radioactive isotopes (like the ones found in bananas) are attached to chemical substances such as glucose that are used naturally by the body
