The Electrome: The Next Great Frontier For Biomedical Technology

It’s got sodium, potassium, calcium, etc., and these ions are charged particles. It doesn’t really like sodium so much. And those are probably where the electrons are, actually, because an ion, it’s got a plus-one charge or a minus-one charge based on— but let’s not go too far into it. This is like sieve water.
