microscopic nano-particles

[particles]

Is it possible for a medication to leave "nano"-particles (smallest sized particle invisible to the eye) penetrated in objects? And if contact with them (the particles), somone who is hiper-sensitive in general and to that particular medication, still feel some residue effects??? Please someone highly knowledgable on this topic solve this mystery!

medications are fully soluble in you body, nothing will be left. anyway, there would be far more particles from the environment(dust and such).

Thank you! -- but what if in the case that there were a least a 2 dozen boxes of crumbled medication (it was a very brittle presentation (soluble in the mouth) in other words, lots of dust of this medication everywhere......can the dust from it some how, in microscopic form, stay somehow penetrated in the objects in came in contact with? and still produce some for of effect on highly sensitive people?

i doubt it as the dose would be incredibly tiny. even if your hypersensitive to it he dose just wouldn't do much.

It would be possible, though I must say I've never heard of crumbly medication and it would be a bad idea. I've heard of someone who died from peanut allergies due to kissing someone who had recently eaten a peanut butter and jelly sandwich. But I've never heard of crumbly medicine, and if you mean pills, they are usually coated with something to make them go down easily, which should keep it from releasing powder.

Well, the medication was in a dissolve in mouth form, and it was always cut in half, and so it would "crumble" much. In addition, the boxes (at least 20 boxes) with much medication dust residue were stored in the room for a long time, at LEAST a year. So this is how the dust came to be. So is this possible?
