In case others like me don’t know what a Majorana particle is: https://en.wikipedia.org/wiki/Majorana_fermion

“A Majorana fermion (/maɪəˈrɑːnə/[1]) or Majorana particle is a fermion that is its own antiparticle. They were hypothesised by Ettore Majorana in 1937. The term is sometimes used in opposition to Dirac fermion, which describes fermions that are not their own antiparticles.”

I am still confused. Are these made of quarks? Electrons? Atoms? Ions?

All the article says is "a new material made from indium arsenide and aluminum".

> Fermions have a half-odd-integer spin (spin 1/2 , spin 3/2 , etc.) and obey the Pauli exclusion principle.

> These particles include all quarks and leptons and all composite particles made of an odd number of these, such as all baryons and many atoms and nuclei

I this it's a way to describe a set of particles or "objects" with certain properties.
