Remdesivir has been shown to inhibit virus assembly by blocking RNA polymerase (for example Article Mechanism of Inhibition of Ebola Virus RNA-Dependent RNA Pol... ).

However, it appears this relatively small chemical needs to be inside a virus-affected cell to work.

A wild idea would be to re-use a virus outer-shell, take out the RNA and put Remdesivir molecules inside.

This nano-material would have the same spikes as the virus, would target the same cells as the virus, would enter the cell in the same way as the virus, but would release Remdesivir inside the cell (as opposed to the viral RNA).

Would this in any way be possible to build?
