I recently came across "drug encapsidation".
So far, I have come to understand that it is a technique to insert drug particles/molecules in the protein shell of a virus, namely the capsid.
But I cannot find a simplified explanation on how to perform it? On contrary, for drug encapsulation, there are many online materials and resources.
My questions are:
How does one perform the encapsidation?
Are the virus gene in the capsid removed and the drug encapsidated?
How does a drug which is masked as a virus not get detected by the body's defense mechanism?
