Project angel’s glow
Technology
A tiny micro bot that gets injected into the blood stream once, and them the host is good for life. The micro bots act like white blood cells and macrophages, or whatever is necessary at the moment. They glow in an adrenaline rush. A person with such micro bots in them should not get sick, have allergies anymore, and heal at an accelerated rate. They’ll also be glowing green in an adrenaline rush.
When first injected, the host will feel cold, and like their skin is crawling. Very uncomfortable for 3 days tops. If the host starts to vomit blood, their body is rejecting them, and they must be removed immediately.
if the host does not reject them, after two weeks, they cannot be removed without harming the host.
Small plastics and non-magnetic conductors.
Almost nothing

Healing abilities, i guess.
Note: the person with these in their bloodstream is not magnetic. Thank you for your concern, they can still hold magnets.
